The second trimester of your pregnancy is from week 13 to week 28 - roughly months four, five and six.
As well as feeling and looking more pregnant during these weeks, you may also have more energy than you did in the first trimester. This will come as a great relief if you have been struggling with sickness, tiredness or anxiety about getting through the first trimester.

As you go through the second trimester, you’ll gradually see your 'bump' grow and later you'll start to feel your baby moving.
Choices and decisions in the second trimester of pregnancy
You have the right to say no to any test or scan that's offered. It is always your choice and the team looking after you will respect your decision.
If you haven't already thought about it, it’s a good time to start thinking about where and how you would like to have your baby. From home birth to hospital birth, you may have to make a decision. If this all seems a little scary, don't worry. Your midwife will be there to support you and tell you what your choices are. You'll go from beginner to expert in just a few weeks!
You may want to consider whether to ask if you’re having a boy or a girl when you have your scans. This is a very personal decision – some parents are excited to find out and others prefer to be surprised at the birth. Keep in mind, though, that a scan doesn’t always show the sex of the baby and sometimes what you are told could turn out to be wrong!
If you are still smoking – even if it’s just the odd cigarette – check out your local stop smoking options. If you stop smoking before the 15th week of pregnancy, the health risks for your baby go down. Stopping smoking is one of the best things you can do for the health of your baby.
Experts agree that staying active in pregnancy is good for you and your baby. You can prepare your body for the challenges of labour and being a mum by keeping yourself healthy and active during your second trimester.
Welcome to the second trimester of pregnancy, a trimester of growth where your bump will get bigger and you’ll start to feel your baby moving.
Your growing baby is now around the size of a kiwi fruit, measuring about 85mm from the top of their head to the bottom.
Your baby is about the size of a small pear.
Your baby is now about the size of a lemon.
Your baby is about the size of an orange, about 12cm long, and weighs roughly 150g. Your bump is getting bigger.
Your baby measures about 14cm this week - roughly the same as a bell pepper!
Your baby is now around the length of a banana and you may be starting to feel them move. You might even start to feel them actually prodding or kicking you!
If they stood up straight your baby would be around 26cm tall, nearly the length of an A4 piece of paper!
Wow - you're halfway there! Your baby is growing hair and starting to look much more like the baby you’ll meet at the end of your pregnancy.
Your baby now weighs around one pound. From around now, they start to weigh more than the placenta. They’re about the size of a bag of sugar.
Your baby is about 30cm now and roughly the size of a large mango.
Your baby is now about the size of a corn on the cob.
Your baby can respond to light, touch and sound now. You might even notice them jumping or kicking in response to a loud noise.
If you could see your baby, you might notice their eyelids open. They’ll soon be blinking.
Your baby’s about the size of a cauliflower now.
Your baby weighs about 1kg now and is roughly the size of an aubergine.

Hi, I'm jaz and near about 20 week pregnant but I'm not feeling the baby's movement,
Is it normal?
By Midwife @Tommys on 11 Mar 2019 - 15:13
Yes Jaz, this is quite normal. If you haven't felt any movement by 24 weeks you should tell your midwife. Take care x

I have a toothache and it was very painful. I can't even sleep well. What is the best medicine for my toothache? I'm 16week Pregnant.
By Midwife @Tommys on 20 Feb 2019 - 15:11
Hi Jonafe. If you live in the UK, dental care is free during pregnancy, so please go to see your dentist as soon as possible. Please do not take any medication other than paracetamol for pain relief during pregnancy and make sure you do not go over the recommended daily allowance.
All the best, Tommy's Midwife

I did a pregnancy test, it came up positive. in few seconds it went off, am really scared. am I still pregnant
By Midwife @Tommys on 14 Feb 2019 - 16:13
Hi Lilian, Thank you for your comment.
If the test showed positive and then faded it should still mean that you had a positive test and it can fade after a time. As long as you read the test in the time instructed on the packaging then this is the result you take. If you are unsure then we would recommend that you do another test to check for a positive result. Take Care, Tommy's Midwives x
By Jemma (not verified) on 1 Dec 2018 - 02:53
Hello, I have been having on and off pain in my vaginal area and what feels like the inner hip joints. It usually fades when I change position. I'm a bit worried. Should I see my doctor?
By Midwife @Tommys on 3 Dec 2018 - 14:55
Sorry Jemma but I am not able to help you without more information. I suggest you talk to your midwife or doctor for advice. Best wishes

I am not clear what you mean, would it be ok to drop us an email and we can talk in more detail? Our email address is [email protected]
By Katie (not verified) on 19 Nov 2018 - 16:29
I had very mild spotting, light pink and only once when I wiped, last week @ 14 weeks. Spoke to the midwife that night and again in the morning as it happened again. As I had no cramping they weren’t concerned. The midwife did say I could attend the MAU for a scan but I wouldn’t be classed as urgent and may have to wait a while to be seen - it’s over 60 miles away so decided to leave it and keep an eye on it. It stopped and I felt fine.
It happened again yesterday, after sex, which I was kind of expecting and it wasn’t as much as last week and again I felt fine. I didn’t call the midwife as I wasn’t worried and decided to call today just to make them aware. The midwife I spoke to this time was very dismissive and told me that because at 12 weeks the baby was fine I wouldn’t be scanned again and I would need to wait until my 16 week check next week when they will listen for a heartbeat. She also said it’s my choice if I want to avoid sex or not.
I don’t know if I should push for another scan or just except that they’re not concerned and wait until next week?
By Midwife @Tommys on 21 Nov 2018 - 12:56
Hi Katie. It would be useful for you to find out what is causing this, particularly if you continue to bleed off and on. It is quite possible that it is linked to cervical changes or to sexual activity and you may not find the cause. However, ideally you should be seen and have a vaginal or pelvic assessment. You may also be advised to have a blood test to check your hormone levels or to check for infection. Try to talk to your midwife again or see your GP for advice. Best wishes
By Katie (not verified) on 24 Nov 2018 - 10:35
Thanks for the reply.
I had more spotting on Tuesday night which then turned into what I felt was a bleed - I felt it when I stood up and it had soaked my knickers. I had already spoken to the MAU and they advised me to go straight in.
I was checked over - baby fine and happy and my cervix looks as it should.
Very scary but glad it was ok as I was convinced it was all going wrong. No spotting since and only brown discharge which has now stopped too.
Looking forward to my check up at 16 weeks this coming week to hear the heartbeat - haven’t heard it since 8 weeks!!
By Dorathy (not verified) on 16 Nov 2018 - 09:44
Am 13wk pregnant and am bleeding it started light and it increases and my doctor prescribed a drug to me (biopentin) and am still bleeding which drugs should I take again to stop the bleeding
By Midwife @Tommys on 16 Nov 2018 - 10:45
I am afraid that biopentin is not a drug that is used in pregnancy in the UK. If you are still bleeding and having pain then we would advise for you to go back to your doctor for a review.
Best wishes, Tommy's midwife

There are no cramps no bloating no pains I am just as I was before pregnancy . I am not feeling any kind of pregnancy symptoms and and not even my baby. I feel as if my tummy is empty there's no baby in it is normal it's my 14 week
By Midwife @Tommys on 14 Nov 2018 - 11:43
Yes this is quite normal. it isn't possible to feel baby movements until at least 16 weeks and most women report feeling baby for the first time after 20 weeks. Please be reassured.
By Carol (not verified) on 17 Sep 2018 - 18:33
LMP was on 24,25,26,how many weeks am i please?
By Midwife @Tommys on 19 Sep 2018 - 13:12
According to your dates which I presume are for during august, providing you have a regular 28 day cycle then you are about 3 weeks and 6 days pregnant. When you have your first scan this will give you your accurate dating and due date.
By Midwife @Tommys on 26 Sep 2018 - 11:13
Using our link below, you can input the first day of your last menstrual period date/month and input your average cycle length - this will give you your approximate current gestation and estimated due date.
All the best

I have had 3 previous miscarriages at 1 trimester.
I am now 13 weeks 4 days and have had bright red blood this morning and I am on holiday in Spain. I’ve spotted through out slight pink and was scanned at 6 and 8 weeks via Tommys due to previous miscarriages. I then had a small red bleed at 9 weeks went to a&e and was scanned and everything was fine. 12 week scan was also fine.
I’ve now woken up to quite a bit of red blood but not enough to soak a pad. I’m just looking for some advice as I’m in a foreign country. Do you think I should visit a hospital here?
Any advice or suggestions would be great - thank you.
By Midwife @Tommys on 23 Aug 2018 - 14:19
It would be advisable that you are seen at the local hospital there just so that you can be checked over as any bleeding in pregnancy needs to be assessed. If you have your maternity notes with you then please take them in then they can see all your medical history. Make sure you take your insurance details with you and your EU health card so that you can receive treatment if needed because they may ask for them. Hope this helps, take care Tommy's Midwives x

Please am having down back pains, especially if I bend down, carry something, trick for a while and sitting on a low chair. I have tried to control it but its given me concern. Do I need to see doctor for it.
By Midwife @Tommys on 9 Aug 2018 - 16:17
Hi Esther, Thank you for your comment.
We would suggest that if this back pain is becoming debilitating then you do need to see your GP who can refer you too a physiotherapist and they can give you exercises to manage the pain throughout pregnancy. Please call your GP as soon as you can to get an appointment. Take Care, Tommy's Midwives x

Hi there, I'm just looking for some advice as not sure if I should go see my midwife. I am 15 weeks pregnant have had nausea since the begining (ivf pregnancy) and constipation. However i had a bout of diorreah on Sunday night which lasted just the one time and did not happen again nausea has neither gotten worse or better have vomited a few times but not since having the diorreah . I have pain in my abdomen but goes away when I eat and then just feels tight . I had another bout of diorreah again last night (Tuesday night) and the same sensation slight pain until I eat then slight tightening. The tightening is uncomfortable and I'm worried there may be something wrong with the baby but aware that theses symptoms are also respective of being 15 weeks pregnant. Any advice would be much apprecited. Thank you.
By Midwife @Tommys on 27 Jul 2018 - 12:15
It sounds like you have symptoms of a tummy bug, in which case the best thing to do is to stay at home, rest and keep hydrated. You describe that the slight pain goes away when eating which is reassuring and that you have an uncomfortable tightening, but from what you have said it does not sound like they are regular or happening often. If you have pain which is continuing or tightenings then do see your midwife, same if you have any bleeding. If you develop a fever or feel unwell then do see your GP for a review.
By Katrina (not verified) on 1 Aug 2018 - 01:21
Thank you so much for your reply and great advice. I did stay home and keep hydrated I saw my midwife on mon day and was reassured by her and the sound of little ones heart beat. The diorreah did not happen again after the bout last tuesday and I feel much better. Still having the tightening sensation of an evening especially after my evening meal which is making it difficult to sleep but figure this is round ligament pain and digestion. Thank you so much again for your reply.
By Midwife @Tommys on 1 Aug 2018 - 09:33
I am glad to hear all was well and your were checked over.
It does sound like round ligament pain yes, but if it continues or worsens, please get another review to be 100% sure.
All the best
By Alexandra (not verified) on 28 Jun 2018 - 17:22
Hi there! I've been having these irregular and uncomfortable contractions which range from a few times an hour to 4-5 times. I've been to Labor and Delivery 3 times so far this week (here in the US) to be examined, and they have told me each time I am fine and my cervix is closed. Is it normal to have very frequent contractions at almost 22 weeks? I think I'm also feeling round ligament pain as there's a sharp pain every now and then around my uterus. Thank you.
By Midwife @Tommys on 29 Jun 2018 - 11:47
You have absolutely been doing the right thing by going to the labour ward when you have been feeling regular tightenings as it would be unexpected at 22 weeks of pregnancy. Sometimes these can be triggered by an infection, often a urine infection so I am sure that they would have checked for this at the hospital. Sometimes there is no explanation and for some women they have an 'irritable uterus' which really means that they will experience tightenings regularly but cervix remains unchanged. Some ligament pain again can be very normal, but this is usually on going pain rather than tightening type pain. Please do continue to go back to the hospital if you are having regular tightenings that are on going.

Iam suffering from bad caugh since 3 days,i have consulted my doctor but their is no cure,and in 20 days i lost 3kgs of my weight,will my baby wil be fine??please could you explain me in details...i kindly request you...
Iam from india.
By Midwife @Tommys on 6 Jun 2018 - 15:01
According to your Last Menstrual Period date of 15th Jan, you are around 20 weeks pregnant. I am sorry that you are having a bad cough, but this will hopefully soon pass (get the dr to make sure you do not have a chest infection requiring antibiotics.) I am also sorry to hear that you have lost 3kgs of weight. I hope that your doctor is keeping a close eye on your weight loss and will make any referring to a dietitian if needed.
All the best

I am at 12 weeks, I am having a light abdominal pain and vaginal pain sometimes it feels more like a menstrual pain. Is there any concern with the baby, my scan is due next week.
By Midwife @Tommys on 4 Jun 2018 - 14:35
Hi Mousaumi, Unfortunately it isn't possible to reassure you without examining you but some mild cramping is quite common and not always associated with problems. If the pain gets any worse or if you have any bleeding please see your doctor straight away. Take care
By Hawy (not verified) on 1 Jun 2018 - 20:01
I am 13weeks, but I am having severe pain around my lower abdomen including my stomach sometimes. Is it a problem?
By Midwife @Tommys on 4 Jun 2018 - 14:30
Yes, any severe abdominal pain in pregnancy should be investigated. If you are in the UK you should see your doctor immediately or go to A&E.

Hi im sixth month pregnant and all i think about is after birth of my baby i want to to be out of this marriage coz Ive never been happy my fiance is too controlling and that makes me feel uncomfortable to be around him coz he can be abusive too.
By Midwife @Tommys on 16 Feb 2018 - 15:02
It is really important that you get the help and support to make sure that you and your baby are safe. If you are able to, when you see a health professional or your midwife alone then talk to them about your relationship and what you are experiencing and they will support you. In addition or alternatively there are several organisation who will be able to help you, for example you can call the national domestic violence helpline on 0808 2000 247, and that line is open 24 hours a day, 7 days a week. They also have a helpful website too: http://www.nationaldomesticviolencehelpline.org.uk/if-you-are-a-woman-experiencing-domestic-violence.aspx
There are two organisation also, Women's aid and Refuge who will support you and get you and your baby to safe place: https://www.womensaid.org.uk/ and https://www.refuge.org.uk/
If you ever feel that you are in immediate danger then call the police via 999 immediately. IF we can help you further then please do call us on 0800 0147 800 or email us [email protected] Please take care, Tommy's midwives x

I am presently in the UK on scholarship and I have 7months to go. My boyfriend visited over the holidays and we had unprotected sex and I took in. I habe loads of academic work ahead of me and I am required to graduate with a distinction should i want to progress to Ph.D. I have no families here just friends. I dont know if I can pull through with a pregnancy all alone with no support and still do well in my studies. I have thought of an abortion but I am still very very scared. Who can tell me what to expect?

Hi, congrats for being preg. We thk we can plan thgs but nothg is accd to our plan. U can go through the preg all alone all u need is confidence in u that u can support the young once. I am a married women ppl normally tho its easy for me but the fact is right from financial support till bringing up my children my husband helped me in nothg. There r very few women in words whose partner will help. Women's r like lionesses we have capacity to be mother with out any once support. So my suggestion is to be happy and take the challenge in ur life u can do it. If u have studies u will not b studying all day right.plan timr for every thg and all the best

Hi, It is very common for these 'minor disorders of pregnancy' to go at around 12-14 weeks and many women begin to feel much better at this stage. You will be having a scan very soon where you will be able to check that all is well. Hope this helps. Best wishes

I am 19 weeks pregnant. I have started having a lot of skin dryness and itchiness all over the body; especially on the abdomen. this has been happening for the past 2-3 weeks now.
Is it normal??
what can I do to get relief?
moisturizing lotions give a very temporary shortlived relief, is there anything more effective.??
P.S. winter season has kicked in here and I do normally get dry skin in winters but it is never this bad and itchy!
By Midwife @Tommys on 17 Jan 2018 - 13:17
Please go to your maternity unit triage/day assessment asap with your notes to discuss this. They may need to take your blood to test for Obstetric Cholestasis- which is a liver bile acid build up and causes lots of terrible itching all over. It is quite serious and so needs to be diagnosed as quickly as possible. On the less serious end of the spectrum - once this has been rules out, you may have an allergy to something, so some cream/antihistamines(such as chlorphenamine) may need to be prescribed. I would rather that you were seen sooner than later, so please take care of yourself

I'm in my second trimester.. through out my first trimester I was really active and since I'm in my second trimester I'm feeling more fatigue, also I'm losing interest in having sex and pains in my back?? Why is that so
By Midwife @Tommys on 11 Jan 2018 - 09:23
This is a very common occurrence and nothing to be concerned by- hormonal fluctuations can reduce sex drive, sometimes this is short lived, other times this can last the whole pregnancy.
In terms of the back pain though, i would get your urine dipsticked to check you do not have a UTI by your midwife/doctor. If you have any itching, stinging or burning when you pass urine, this could be another sign of a uti.
If you are a clear of uti, then the back pain could simply be attributed to the growing uterus adding more weight to your body and your body learning to adjust and shift its centre of balance. If this is causing you concern, you can speak to a midwife/doctor about it in triage/day assessment unit at your maternity unit. Take care of yourself, Sophie Tommy's Midwife

Hi, I am 15weeks and have been experiencing dull aches and slight stabbing pains back and forth low down in my stomach for the past two days. The feelings aren't strong enough for me to take paracetamol but enough to notice them. Is this normal? A part from that in feeling fine! Just a little worried.
