15 weeks pregnant - what to expect

Baby at 15 weeks pregnant

This week, your baby is around the size of a large navel orange, and weighs about the same as a chicken’s egg. Your body should finally be showing signs of being pregnant, but here’s what’s going on with your baby and the common symptoms to expect at 15 weeks pregnant.

What’s my baby doing at fifteen weeks pregnant?

With each week that goes by, your little one is starting to look more and more like a baby. By week 15, she’ll have ears on either side of her head and her eyes are moving from the side of her head, to the front of her face. Her eyes will start to become sensitive to light, even though they remain closed, she can now register bright light.

But what else is your little one doing in there? Aside from spending lots of time growing, she’s practising breathing, sucking and swallowing so they have all the skills necessary to survive in the big wide world. You still won’t feel it, but she’s also moving around a lot.

Around this time in your pregnancy, your baby will also start to hear muted sounds form the outside world; the noises your digestive system makes (believe it or not, she finds the whooshing comforting), as well as the sound of your voice and heart.

What is my body doing at fifteen weeks pregnant?

As your baby continues to grow and develop, you may notice that you feel permanently bunged up. You could also suffer from nosebleeds and sinus pain thanks to the increased blood flow to the membranes in your nose and sinuses. Avoid rooms with the central heating or air conditioning on full blast, as they’ll dry out your nasal passages.

You might notice around week 15 your gums are red, swollen and sore. They might even be prone to bleeding when you brush or floss. This is down to those pregnancy hormones again. More than 90% of women suffer with gum problems during pregnancy, and this can lead to some nasty complications, so prevention is key. Read more about good oral hygiene during pregnancy here. 

You should also now be gaining more weight as your baby gets bigger. Don’t go overboard, but don’t panic either – aim to gain around one pound a week, or about four pounds a month.

Common symptoms to look out for:

  • Heartburn and indigestion: Now that the morning sickness has (hopefully) eased off, you’re probably feeling a lot hungrier, yet this also causes that uncomfortable heartburn you’re desperately trying to avoid. If you are suffering, try eating several smaller meals, rather than three large ones.
  • Faintness or dizziness: Feeling light-headed is a common side effect during pregnancy, as your blood sugar levels change. If you do feel faint, sit down and put your head between your legs as this will prevent you from falling and hurting yourself.
  • Varicose Veins: We spoke about these last week; as much as you might hate them, they are a normal side effect of the increased blood flow during pregnancy. Sit down and your your feet up – this will keep the blood circulating and reduces the pressure on your legs.
  • Pregnancy brain: Can’t remember when bin day is or where on earth you left your car keys? Pregnancy brain is a real thing as your brain cell volume actually decreases during pregnancy. Now is a good time to start using that notes section on your mobile!
  • Cramps and pains: Medically referred to as round ligament pain, as the muscles and ligaments that support your uterus stretch, you might get pains on the lower sides of your body. This is very normal, but if you’re in too much pain, it might be worth checking with your GP.

What you should be doing this week:

  • Talk to your doctor: If you’re at high risk of preeclampsia, or genetic or chromosomal issues, now is the time to chat to your GP as they’ll do the relevant tests between weeks 16 to 20.
