You're pregnant: congratulations! The first weeks of your pregnancy are a vital time as your pregnancy gets established. While you get used to being pregnant, your body is busy building a baby. How exciting!
The second trimester is the middle three months of your pregnancy. You will start to look and feel pregnant. This is a time when lots of women tell the world they’re pregnant and begin to feel like the pregnancy is more ‘real’.
The end of your pregnancy is in sight. It won't be long until your baby arrives. Feelings at this stage of pregnancy tend to vary from tiredness and worry to excitement about the baby.
What is a trimester?
People often talk about pregnancy as being nine months long. In fact it’s usually slightly longer than this. Your pregnancy is measured from the first day of your last period rather than the day you actually conceived.
A pregnancy generally lasts around 40 weeks, and your dates are referred to in weeks because this is more accurate than talking in months.
Your pregnancy has three phases, called trimesters, and each trimester is about three months long.
Each trimester has its own mix of highs and lows, and you can find out what to expect in this pregnancy calendar. The information in the calendar may be helpful for the people close to you as well.
Although it’s normal to have periods of worry and stress when you’re pregnant, some women have feelings that don’t go away and this can be a sign of something more serious.
People may tell you that pregnancy is a good time to put your feet up. If your pregnancy is uncomplicated it is actually much healthier for you and your baby to exercise while pregnant.
Although you will be putting on weight in pregnancy as your baby grows, limiting the amount of extra weight gain in pregnancy will improve your health and your baby's, both now and in the future.
Most women worry about how they will cope with the pain of labour and birth. You may worry too, especially if it is your first baby and you do not know what to expect.
Sometimes things go wrong during pregnancy and you need extra care
In many cases the symptoms in this section will not lead to a serious complication and will be treated easily. Occasionally though they are signs of a more serious complaint.

Hi I had my period on the 17th of may came off the pill on the 21st bled again on the 4th of june and just got a positive pregnancy test any idea when I conceived?
By Midwife @Tommys on 6 Jul 2017 - 13:27
Hi Kimberly, we can never be really sure about the time of conception as sperm can live in the body for up to 7 days. Normally midwives date a pregnancy from the first day of your last period, which would be 4th June, women tend to ovulate around 14 days after this, so it could be possible that conception occurred around this time but again we can never be sure of the actual time of conception. If you have had a positive pregnancy test and you are unsure of your dates then please see your GP who may be able to refer you for an early scan to see how many weeks you are into your pregnancy. Hope this helps, Best Wishes Tommy's Midwives x

My last period was on the 15th of may 2017 . I had a etopic pregnancy and lost a tube last june 2016 at 5 weeks so im so scared to do a test just hoping this baby will stay im praying it will all go well
By Midwife @Tommys on 30 Jun 2017 - 10:00
Hi, it is totally understandable that you are feeling anxious in this pregnancy and these early weeks are scary for you. According to your dates, if you have a regular cycle then you are about 6+3 weeks pregnant. It is important that you are taking your folic acid supplement and any concerns please see a GP or go to A+E straight away. I am sure you are aware of what to look out for but here is a link to our info if this helps at all:https://www.tommys.org/pregnancy-information/pregnancy-complications/ectopic-pregnancy Take care, Tommy's midwives x

By Midwife @Tommys on 12 Jun 2017 - 09:41
If you are 24 weeks pregnant today and due on 30th September, conception would have been approximately between 4th and 10th January. Hope this helps

Hi, I've posted on here a couple of times before now, while I was pregnant, when I miscarried etc.
I had a confirmed early full mc on 22 March. My first period arrived 29 April - 3 May. I am now experiencing a watery pink discharge on and off, tender breasts, slight cramping and waves of nausea since 8 May.
Is this just my hormones still sorting themselves after the mc? Ovulation bleeding, or is it possibly implantation?
By Midwife @Tommys on 10 May 2017 - 15:04
I am sorry to hear of your miscarriage, i hope you are doing ok?!
It is difficult to know. If you have had a full, normal period and then had unprotected intercourse between the 3rd May and now, then it is possible that you have conceived again. However, it would be too early for you to be feeling nauseated and have tender breasts due to another pregnancy within less than a week as the hormones do take a few weeks to build up in your system before they begin to make you feel this way.
If the pain, discharge and cramping continues for over 24 hours, I would seek medical review - either with your GP or at an early pregnancy unit.
Please take good care of yourself.

I lost twins in December at 9 weeks. I have found out i am pregnant again, i had 2 normal periods and missed Aprils and took a test which was positive. My last period was 8th March. I am just so anxious i will miscarry again.. I had a awful experience in Dec and ended up having a womb infection. I am just so concerned i will have another missed miscarriage..
By Midwife @Tommys on 26 Apr 2017 - 14:50
Thank you for posting. I can only imagine how nervous you must be after losing your twins in December.
Your GP can arrange an early ultrasound scan at around 7 weeks for reassurance. Early Pregnancy Units will accept referrals of women who have had a previous loss – so it is worth speaking to the GP about this and also discussing fears and anxieties so your GP can support you.
Please be reassured that anxiety in pregnancy can be very common, it is worth knowing that NICE Guidelines suggest that GPs refer pregnant women suffering from anxiety or mild depression in pregnancy for counselling (short-term talking therapy or CBT). This referral can be fast-tracked under a programme called IAPT ( Improved access to Psychological therapies) . Speak to your GP if you feel the anxiety is overwhelming and request a referral as soon as possible.
This will not only help you with managing your pregnancy but treatment in pregnancy for high anxiety/depression will also significantly reduce your risk of developing postnatal depression.
Please know that we are also here to listen and many women call us in the early days of pregnancy where every day feels like a lifetime. Tommy's PregnancyLine is 0800 0147 800
With very best wishes in this pregnancy

I had a miscarriage at the end of January start of February and I didn't gave a period in between before getin pregnant again I found out on the 19th of march I was pregnant I'm just wondering wen I cud of got caught and how many weeks I am thanks.
By Midwife @Tommys on 18 Apr 2017 - 09:56
I'm so sorry to hear of your miscarriage earlier this year - I hope you had support and care given to you during such a difficult time.
It is possible to get pregnant straight after a miscarriage - I would advise that you arrange an appointment either with your GP or your local midwife if you can for early pregnancy care as well support and advice on determining how many weeks pregnant you are.

have just found out I'm 4 weeks pregnant, haven't officially been to gp but have done 2 positive tests. I suffer from GAD generalised anxiety disorder and I just worry now I will do my baby damage with excessive worrying. I don't take medication, I have taken sleeping tablets in the past and would like to ask my gp if occasionally I need to take one to get some sleep before work can it cause serious problems? PS Now the fun begins!!!
By Midwife @Tommys on 23 Feb 2017 - 14:00
Hello and congratulations on your pregnancy. Remember that any medication taken in pregnancy should be under the guidance of your doctor only and it would be sensible to discuss these issues at your appointment soon. Also it would be worth thinking about your exercise regime as, If you weren't very active before your pregnancy, there are lots of small changes you can make in your day-to-day life that will make a big difference to your physical and mental health which will positively impact on your baby. Good luck and keep in touch

Found out I'm pregnant about 2 weeks ago I feel like i can already feel him or her moving and my belly already swelling is that normal or do you think I'm further along? Possible advice would be very welcome and appreciated thank you x
By Midwife @Tommys on 20 Feb 2017 - 09:19
Congratulations on your pregnancy news - I hope you are keeping well.
Whilst it is too early to be feeling baby's movements what you may be experiencing is changes in your digestive system adjusting to pregnancy. Often women can feel bloated, full, windy or constipated due to hormonal changes in early pregnancy.
If you haven't already make an appointment to see your GP so you can be referred for antenatal care.

I'm not sure of my due date. I know it works of the first day of your last period however I was spotting three days before? So do I go by the spotting date? Or my actual period?
By Midwife @Tommys on 17 Feb 2017 - 11:02
We would initially date a pregnancy from the first day of your actual period until you have your initial dating scan between 11-14 weeks of pregnancy, this scan will then give you your final estimated due date for the pregnancy. Take care, Tommy's Midwives

Hi. I've calculated my due date and the days I Conceived are pretty accurate as I know when I had intercourse however my ultra scan told me I'm 13weeks when I thought I was 11weeks and when I count back 13weeks on the calender, it falls on the first day of my last period. I don't get it i had sex at the end of November to the beginning of December
By Midwife @Tommys on 16 Feb 2017 - 15:28
You are correct. A pregnancy is dated from the first day of your last period and not from the date that you had intercourse. That would therefore mean that you are 13 weeks.

I only found out last week I am pregnant! With my second. I'm not sure how far gone i am as I have missed 2 periods and my midwife appointment is on the 23rd February. I think I'm further than 8weeks as I'm getting symptoms and feelings that I had with my son when I was around 15 weeks.
Hope someone could help and hope it made sense. Thank you x
By Midwife @Tommys on 13 Feb 2017 - 09:15
Hi Georgia. Congratulations on your second pregnancy.
Using our pregnancy calculator, you could enter the date of the first day of your last menstrual period, and the average length of your cycle to work out roughly how many weeks pregnant you are and when your baby will be due. If your dates are unclear, then your first ultrasound scan with give an estimation based upon the measurements of your growing baby.

I had a silent M/C at 8 weeks and found out at my 12 week scan. They took me in for an evacuation procedure the same day on the 4th Jan 2017. I bleed for around 7 days after this but I have not had a period since. I took a pregnancy test and it said I was pregnant but my HCG levels are only 10. Could this be left over residue of the old pregnancy or a new pregnancy. I am so confused. I have taken three tests 2 of which were positive and one last night which was so feint that it makes me think I am loosing my baby again. Is it possible that the tests are just detecting my old pregnancy? Any help very much appreciated. I hope all that made sense :)
By Midwife @Tommys on 10 Feb 2017 - 11:30
Firstly I am so sorry to hear that you have been through a miscarriage recently. Yes you do make sense and absolutely it can be a little confusing. It can take several weeks for your hormone levels to return to under 5 (non-pregnant level), it is possible for this to take up to 6 weeks and varies depending on the pregnancy and the woman. It is possible that the pregnancy tests are still showing up from the pregnancy that you miscarried, however it is also possible for you to have ovulated and become pregnant again if you have had intercourse during this time. How strong or faint the line is does not necessary tell you how strong the hormone level is within your body. I would suggest to repeat the pregnancy test in about 5 days time, if positive then see your GP for blood test and see if the hormone level is rising sufficiently for another pregnancy. If the test is negative then it shows that the hormone level has fallen enough to non-pregnant levels. I hope this helps, if you would like to talk further please do email us [email protected]

Hi, thank you for posting most women start to feel their baby move between 16 and 24 weeks so you have a few more weeks to wait until you feel movement. After your scan you will be made aware that your little baby is already super active, growing and developing you just don't feel the movement yet as he or she is still so tiny ( 30 mm at 10 weeks).
Wishing you a healthy pregnancy!

Hey there im 7 weeks pregnant and over the last few days ive gotten a bad itchy rash all over my legs and starting a bit on my arms is this normal during pregnancy? And what can I do to make it go? Im taking Elevit and wondering if that could be the reason?
By Midwife @Tommys on 16 Jan 2017 - 09:24
Hi Maureen. Pregnancy can cause changes to your skin, some of these are deemed to be "physiological" or normal, and others can be a cause of concern. It is best to consult your GP/doctor/midwife as soon as possible with any rash that is sudden or unusual for you. Some rashes are specific to pregnancy, some are non- specific which can occur at any time in life and some is an itch, with no rash. You may be given treatment if necessary, but you certainly need to be reviewed before the type of treatment could be started. Sometimes it might be necessary for you to have a blood test too.
Take care of yourself
