15 weeks pregnant: advice, symptoms, and what to expect


by Stephanie Anthony |

At fifteen weeks pregnant, our body should finally be showing signs of being pregnant. Here’s what’s going on with your baby, your body, and the common symptoms to expect at 15 weeks pregnant.

How big is my baby at fifteen 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.

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 15 weeks, they will have ears on either side of their head and their eyes are moving from the side of her head to the front of her face. The eyes will start to become sensitive to light, even though they remain closed, they can now register bright light.

But what else is your little one doing in there? Aside from spending lots of time growing, they are 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 they are also moving around a lot.

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

1) 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.

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 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 from gum problems during pregnancy, and this can lead to some nasty complications, so prevention is key. Keep up good oral hygiene during pregnancy and you'll be fine.

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.

What you should be doing this week:

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