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.

Have been menstruting every month but I still feel am pregnant so I used the pregnancy kit and the result was negative .I went to hospital for the blood test(pregnancy) but the result was still negative after that have done the ultrasound but they still can't see the baby in my stomach .am 9wks pregnant. So please am I pregnant??
By Reptarsmama (not verified) on 15 Oct 2019 - 03:37
Sweetheart, I'm no expert but I know that PMS can mimic pregnancy symptoms. If the test is negative, the blood test is negative and the scan are all saying no...I'm thinking that it's safe to say you aren't pregnant. Best of luck.
By Shelby (not verified) on 16 Jan 2020 - 08:27
What makes you think you pregnant, I had a ultra sound at 7 weeks and they found the baby right away so I’m not sure why they wouldn’t of found your baby, have them check you for cyst on your ovaries some times they can cause you to look and feel pregnant

Oh my gosh yes, I've just hit 20 weeks and am just now starting to feel the baby move. Until about 12 or 13 weeks I felt terrible and didn't even really feel anything about a baby except the bad symptoms of being pregnant.

It's my 3rd pregnancy and I'm 12 weeks along and I still don't feel pregnant and cant believe there's a baby in there.I think it's normal to feel this way because it's so early on.
By Anna (not verified) on 23 Aug 2019 - 15:16
Hi Clysta, am Anna. Of course it’s normal at 10th week. But there is a baby in your belly trust me. By 16,20week you will feel the movement. It’s nothing to worry. Your baby is fine.

I’m 14 weeks with number 2 and it is normal to know your pregnant but not “feel pregnant” I’m the same at the moment but once you feel those first movements it will hit you hard that you are pregnant lol. Give it time it will sink in.

Hi I'm 8 w6days pregnant, yesterday had an ultrasound scan, no fetal heartbeat seen, when I gone for 6 w6 days there was a very small tickling seen, doctor confirm the heartbeat, now at present doctor told its a missed miscarriage, why is it happened, and he ask me to wait for 1 week for the next detailed viability scan,he continued if there is any bleeding or cramping, I should meet the doctor immediately, I feel normal, I hope everything will be ok, should I expect the heartbeat next week, is there any successful stories? Please reply

By Margaret (not verified) on 24 Jun 2019 - 00:35
What I would recommend is contact your doc have in schedule ultra sound so they can see and if you wanna know a little bit ahead just count from the day you took your test and say at least a month comes a least a month so = 4 weeks
By Baby (not verified) on 11 Jun 2019 - 14:07

Hi - Thank you for your message.
if you LMP (last Menstrual period) was 25/11/2018 then you would 21+4 weeks pregnant today.
By kylie (not verified) on 30 Apr 2019 - 17:23
Given if your start date of your last period was the 25th of november and your cycle is typically 28 days then you are 22 weeks and 2 days along as of april 30 2019.

Hi, am 14 weeks now but no longer feel pregnant. I just feel headaches, pain in thighs and little cramping which I wonder if it's normal, my baby bump is not even showing,am flat and don't feel the baby moving. Is my baby fine? or I should go for a check up
By Midwife @Tommys on 22 Mar 2019 - 11:20
You have had a scan recently which I hope was all OK and no concerns from this, however if you have concerns and are worried then do contact your midwife for a review.
By Jaz (not verified) on 10 Mar 2019 - 03:57
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 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!!

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.
