15 weeks pregnant - all you need to know

Your baby is about the size of a small pear.

15 weeks infographic.

What does my baby look like in week 15?  

Their hearing is developing and from around now they might be able to hear your voice, the comforting sound of your heartbeat and muffled sounds from the outside world.  

They might also start to sense bright light outside your tummy.

Your baby is covered in fine hair, called lanugo. This will usually disappear some time before they are born, unless they arrive early.

This week your baby might start to get hiccups every now and again. Later in your pregnancy, you’ll probably be able to feel little rhythmic flutters when your baby gets them.

Your pregnancy symptoms in week 15

Any morning sickness and tiredness may have lifted by now so this is a good time to become more active. Swimming, pregnancy yoga, walking or just staying on your feet as much as possible during your normal daily activities will all build your strength for the birth and afterwards.Find out more about exercise and activity in pregnancy.

Itchy skin?

Is your skin feeling itchy on your growing bump? This is probably caused by your skin stretching. If so, it’s nothing to worry about. You could try massaging some unscented moisturiser into the skin. You might notice stretch marks, read all about what they are and what you can do about them here.

Severe itching, particularly on hands or feet could be the sign of a serious pregnancy complication called obstetric cholestasis. Find out more about the symptoms of OC/ICP here


You can be more prone to this fungal infection in pregnancy. If you notice any of the symptoms of thrush, have a chat with your midwife about treatment.


You might have a stuffy nose or suffer from nosebleeds. Hormonal changes and the increased blood supply in your body can put more pressure on the blood vessels in your nose, causing them to break.

This is pretty common but if your nosebleeds persist, tell your doctor or midwife.

Are you suffering from headaches, cramps, swollen feet or indigestion?

Here’s our guide to 10 common pregnancy complaints (and how to avoid them).

What to do in week 15

Keep moving

Being active during pregnancy will boost your health – and it’s good for your unborn baby, too.  Now that your bump is becoming more obvious you may feel as if you need to protect it more, but it’s safe to exercise right up to your due date as long as you feel okay.

There are a few types of exercise to avoid, such as scuba diving and contact sports, but it’s fine to continue with most of the exercise you did before pregnancy.

If you weren't very active before your pregnancy, it's not too late to start. Walking, swimming and pregnancy yoga or pilates are all good ways to get more active. Start with 10-minute bursts and build up to 30 minutes a day if possible.

“Yoga was fab. It really helped. My labour was amazing and quick and I'm sure it was down to great yoga instruction.” Kelly, mum of one

You don’t have to do a formal exercise class. Climbing the stairs instead of taking the lift or getting off the bus a stop early all counts as exercise.

If you want something more specific, look for antenatal exercise classes at your local leisure centre or ask your midwife about classes for pregnant women in your area.

Taking sick leave during pregnancy

If you need to take time off work for a pregnancy-related illness, it doesn’t count towards your sickness record.

If your manager usually provides sick pay you will still be entitled to this. If your company doesn’t offer sick pay you can apply for statutory sick pay. Find out more about a working pregnancy.

      How was the rest of your pregnancy past 15 weeks?

    • By Aji (not verified) on 18 Jun 2019 - 13:30

      I'm 15weeks preg. But in the last few days, all feelings of preg like vomiting, nausea and bowel movement which I felt last week, ceased abruptly. Right now, I feel like I'm not pregnant at all. Should I be really worried please?

    • By Heide Mdaka (not verified) on 1 Aug 2019 - 10:23

      You have now entered the second trimester and most of what you were experiencing during your first cools down. This is where you will begin to enjoy your pregnancy. it's called the honeymoon, so worry not.

    • By bg (not verified) on 9 Sep 2019 - 15:01

      Hi, that's just you settling into your second trimester, it felt as if it was sudden for me too

    • By Dorothy chy (not verified) on 31 Oct 2019 - 21:01

      Hi, It's very normal to stop feeling sick at this stage you are right now. Feeling nausea, fatigue and vomiting usually stops after the first 12 weeks of pregnancy. You're definitely still pregnant it's just your pregnancy hormones had started to settle and you feel more like your self now. But if you're worried at any time, you can contact your doctor or midwife. I know this cos I have a son and 14weeks pregnant now. Good luck to you hon, and congratulations :)

    • By Julie (not verified) on 21 Nov 2019 - 14:13

      No don’t worry! First trimester symptoms like nausea, vomiting, headaches, etc. disappear in your second trimester (usually). I had started feeling like this to and wondered why I was all of a sudden feeling normalish for the most part haha! As long as there’s no bleeding. I wouldn’t worry :) I had my 15 week prenatal appointment Monday. I worried I wouldn’t hear a heartbeat!! It came through loud and clear. Best sound ever

      Hi ,i am five weeks pregnant and i can not lie on my left side nor back. What should i do?

    • By Brittany (not verified) on 25 Jul 2019 - 03:37

      You aren’t supposed to lay on your back as much because your uterus is becoming more heavy, I struggle with the same problems so I use a pregnancy pillow or blanket and lift my top leg slightly and it seems to help

    • By Chris (not verified) on 6 Jun 2019 - 10:35

      Am 15weeks pregnant but it look has if I am not pregnant and my breast is big but not strong ,what should I do

    • By Ellen (not verified) on 14 Apr 2019 - 07:29

      I’m 15 weeks pregnant and have a BMI of 39.When I went for a scan at 14 weeks it was of very poor quality, The sonographer never mentioned anything but just that maybe I didn’t drink enough water but when I read my chart outside it said Restricted view due to high BMI.Im devastated, we couldn’t even see a hand on the scan
      I called my midwife the next day and she explained this can be the case and at my big scan at 22 weeks the same problem might happen.
      I’m so embarrassed if this happens in front of my husband and also very guilty that we won’t get a big picture because I never did anything about being overweight!

    • By crystal (not verified) on 28 Mar 2019 - 16:07

      having cramps since my second trimester am 15 weeks ,these cramps goes and come sometimes they are Sharpe pain its like i feel movement ,in my stomach get hard in different places at times. but no discharge or bleeding my doc say i need bed rest but why?

    • By Midwife @Tommys on 24 Apr 2019 - 10:43

      Hi Crystal
      Cramps are fairly common in pregnancy but should always be assessed by your midwife or doctor. I would suggest that you discuss this further with your doctor as to why they have said you need bed rest. The following link has more information for you about the causes of stomach pain in pregnancy-
      If the cramps become more severe, not going away, there is bleeding or you feel otherwise unwell, then you should go to your local A&E for urgent assessment

    • By Patrice (not verified) on 8 Jun 2019 - 19:53

      This could be caused by round ligament pain which you would experience in the second trimester of pregnancy totally normal. Its because of your stretching uterus making space for your growing fetus

    • By Lee (not verified) on 9 Sep 2019 - 22:23

      I need urgent advice please
      I'm 15 weeks pregnant and i have been having headache since 3 weeks now
      Sometimes even my neck hurts
      I'm scared what should I do?

    • By Anonymous (not verified) on 12 Jun 2019 - 02:05

      If this is your first pregnancy what you're feeling is more than likely your uterus stretching as part of the normal process to prepare for baby full term. Don't stress, keep with exercise right for your comfort and stay hydrated.

    • By Palesa (not verified) on 27 Mar 2019 - 07:31

      Hi I'm 15 weeks 5 Days pregnant as at 27.03.19, I have had a miscarriage at 11 weeks 3 days last year, I went to a specialist after to try find out why I had a miscarriage and I found out I have a bicornuate uterus. Now I'm pregnant again and the baby is in my left horn is there anything that can be done so that I don't loss this baby or have preterm labour.
      please help.

    • By Janet (not verified) on 20 Mar 2019 - 17:48

      Hi, please am in my 15 week but my bumps seems like nothing is in.

    • By Midwife @Tommys on 21 Mar 2019 - 16:52

      Hi - Thank you for your message.
      It is not unusual to not have a visible bump at 15 weeks - particularly if this is your first pregnancy. As your pregnancy progresses and baby grows you will start to notice a change.
      If you are worried about the growth of your baby - discuss it with your midwife during your next appointment.

    • By liza (not verified) on 8 Mar 2019 - 23:58

      please help at the hospital they want to terminate my pregnancy i don't know wat to do

    • By Midwife @Tommys on 11 Mar 2019 - 14:28

      Hi Liza, If you would like to call us, our number is 0800 0147 800. This sounds a really difficult situation for you. Please try to speak to the doctors until you understand the reasons why they advise termination. Sometimes, if the mother's life is a risk, termination is a choice to save the life of the mother. However, if they are able to treat you effectively and save the pregnancy, I am sure that you would want to discuss it further. Best wishes Tommy's midwives

      Hi, I'm 15 weeks pregnant and my morning sickness has yet to subside in the last, any advice as to when it might lessen

    • By Midwife @Tommys on 27 Feb 2019 - 11:18

      Hi Kyla, I am sorry to hear that you are still suffering from nausea and vomiting. Here are some links below that you will find useful reading -
      If you have not been reviewed in your maternity unit triage by a midwife and obstetric doctor, and are still feeling awful, then please take yourself in as soon as you can, with your pregnancy notes, for urgent review. Some women need anti- sickness prescribed for them.
      Take good care of yourself - Tommy's Midwife

    • By Kikiep (not verified) on 26 Jan 2019 - 09:42

      I was about two months pregnant and I had something that seemed like a miscarriage, I bleed heavily for about an hour and some tissues passed out of my virgina. But now it's been 4 weeks since that happened and I still feel pregnant

    • By Midwife @Tommys on 29 Jan 2019 - 13:46

      Hi Kikiep, it sounds like you need to visit your GP to discuss your symptoms. They may need to scan you or to at least review your menstrual cycle. All the best, Tommy's Midwife

    • By Ev (not verified) on 1 Oct 2018 - 10:28

      I constantly get vaginal itching ever since I stated my 2nd trimester,any solutions please, thanks

    • By Midwife @Tommys on 1 Oct 2018 - 16:24

      It is possible that you may have 'thrush'. This is quite common in pregnancy and happens if the normal balance of bacteria in the vagina changes. Typically this can be after taking a course of antibiotics or being unwell. Speak to your midwife or GP who can prescribe a cream or pessary. There is some good advice and do's and don'ts on the NHS website

    • By Chi (not verified) on 17 Jul 2018 - 21:26

      Hi everyone... am 15 weeks along today but i have been having string like mucus running downn my throat since 8 weeks that makes me vomit both food and water all day! Anything cold,milk or milk products is a no-no! My previous two pregnancies (6 years ago)were so easy but this one is a different story because am sick all day with frequent blackouts. I have been to the hospital and given drugs but still no relief, just told to endure! So frustrated! Any help?

    • By Midwife @Tommys on 18 Jul 2018 - 14:42

      Hi Chi
      I am sorry to hear that you are not feeling great- hopefully you will start to feel better soon!
      Have you been to your Gp to see if they can prescribe you anything additional? It sounds unlikely that they will have anything additional if the hospital have already seen you.
      To be honest, i'm more concerned about the blackouts? Have you had your bloods taken to test your iron levels?

    • By Vicky (not verified) on 18 Jun 2018 - 19:06

      I'm between 12-13 weeks pregnant and for some weeks now I've had this serious headache and discharge. At what stage does throwing up set in at pregnancy?
      Thank you

    • By Midwife @Tommys on 21 Jun 2018 - 16:28

      Dear Vicky,
      You may not throw up at all, some women do not experience any nausea or vomiting in pregnancy whilst others experience it very badly. If you have a serious headache then I would advise for you to speak with your GP or midwife as soon as possible so that you can be reviewed any thing more serious can be ruled out.
      Best wishes

    • By Midwife @Tommys on 21 Jun 2018 - 16:26

      Dear Kimberley,
      If you were 11 weeks' exactly on the 19th of May then you are now about 15 weeks and 5 days.

      hi!I'm 15 weeks pregnant bt i dnt feel my bby move n its my third pregnancy

      should i be worried

    • By Midwife @Tommys on 15 May 2018 - 09:46

      Hi Bophelo
      Most women start to feel fetal movements for the first time between 16-24 weeks. So it is still quite early for you to be feeling them at 15 weeks, especially if this is your first baby. Have a read of the link to our webpage below.
      You have no reason at all to worry at this gestation and will soon start to get fetal flutters of movement.
      All the best
      Sophie,Tommy's Midwife

      Hi I'm 15 weeks preg but when l urinate l feel sharp pains like cramps for 2minutes is it normal

    • By Midwife @Tommys on 19 Apr 2018 - 15:53

      Hi Fortune, Thank you for your comment.

      From what you have described, it sounds like you may have a urine infection, this can cause you to need to pass urine more, can burn when urinating and cause pain. You need to call your GP or midwife and then they can test your urine for any signs of infection, they will be able to give you treatment if needed. Keep drinking plenty of fluids at this time at least 8 glasses of water per day. Hope this helps, take care, Tommy's Midwives x

      lm 15 wks pregnant and on not feeling any movement but l have a problem of back ache

    • By Midwife @Tommys on 19 Mar 2018 - 16:55

      Hi Privy,
      We would not expect you to be feeling movements from the baby yet. It is too soon. You may find relief for your backache by seeing a Physiotherapist or and Osteopath, or you may find it helpful to start exercising (If you don't already). We have lots of research to show that exercise is helpful for both backache and pregnancy.
