15 weeks pregnant - what to expect

Your baby is about the size of an apple.

15 weeks infographic.

What does my baby look like?

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 symptoms - what to expect

Any morning sickness and tiredness may have lifted by now so this is a good time to become more active. 

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.

What to do if the itching is severe.


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).


Your gums may be bleeding more in pregnancy, too, as the pregnancy hormones make your tissues more puffy and delicate. 

Use a soft toothbrush, clean gently and visit your dentist for a check-up. NHS dental treatment is free during pregnancy. 

Actions to take

Keep moving

Try to stay active. 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.

Don't slouch on the couch

You may be tempted to crumple into a chair after a long day, but be careful. It isn't good for your back.

Bring your feet closer to the chair and push your bottom well into the back of the chair so that your back is supported. Use cushions if that helps.

Off sick?

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

If your boss 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.

Here are 10 tips for staying active during pregnancy.

    I had a one pad bleed during my third 15 week pregnant and I bleed sometimes often .scanning reports say baby is fine and doing good. I know it's not gud to bleed during pregnancy.but I am worried about my baby

    Any bleeding in pregnancy should be investigated. If you experience any fresh red bleeding with or without pain, or accompanied by any other symptoms, then it is important to make contact with a health professional to be seen as soon as possible. If you experience bleeding often please ask your doctor for the reasons and remember that you can ask advice each time it happens. Best wishes

    My baby is 104 grams at 15 weeks but I read on different websites at 15 weeks baby weight is 70 grams m worried about it but doctor said it's normal

    Hi Thank you for your comment.

    It is difficult to comment on your question as we cannot see your scan report. But if the doctor has said that the growth of baby is normal then try not to worry unnecessarily . All babies grow at different rates and are not all born the same weight. If you are still worried about this then you should contact your doctor or midwife who can talk you through the scan report and answer any concerns that you may have. If the doctor was concerned about your baby in any way then they would of given you another appointment to be seen and monitored. Best wishes Tommy's midwives x

    Hello I'm worried is it normal not to feel the baby move around at this time at 15 weeks and this is my second x

  • By Midwife @Tommys on 4 May 2017 - 11:56

    Yes this is quite normal. Most women report movements starting from 16-24 weeks. We have heard of women experiencing flutters before 16 weeks but this isn't common. If you haven't felt any movements by 24 weeks you should tell your midwife but at this stage try not to worry. Best wishes

    Is it normal to NOT feel movement at 15 weeks? And is it normal to faint? It's my first baby and I'm just worried..

  • By Midwife @Tommys on 6 Mar 2017 - 09:32

    Hi Kirby. With your first baby, it is likely that you will not start to feel any movements until about 17 weeks onward. Women who have had a baby before can often identify movements from as early as 14 weeks, but only as they have experienced these sensations before and notice them earlier.
    Feeling faint is something that needs to be investigated as soon as possible. You could have a very low iron level in your blood which could make you feel faint or induce you to actually faint. If your iron is low - you can visit your midwife or GP for a blood test - then you will be prescribed iron tablets or further treatment depending on how low your iron level is. Please go to visit your GP/Midwife as soon as possible. Please take good care of yourself!

    I feel the movement of my baby when i eating something cold like water mellon nd ice cream.

  • By Midwife @Tommys on 17 Jan 2017 - 14:23

    Congratulations on your pregnancy!
    There is no set number of normal movements. Your baby will have their own pattern of movements that you should get to know.
    From 16-24 weeks on you should feel the baby move more and more up until 32 weeks then stay roughly the same until you give birth.
    The same rule applies to 'looking' pregnant - some women show earlier than others and women also look pregnant in different.
    Try to enjoy your pregnancy - but if you have any concerns please don't hesitate to speak to your midwife.
