In our pregnancy week by week guide, you can find out what to expect when you’re 15 weeks pregnant.

You at 15 weeks pregnant

Your body is circulating about 20% more blood than usual. Your heart is working harder. This might give you a pregnancy ‘glow’, along with a few side effects:
  • higher or lower blood pressure
  • nose and gum bleeds
  • headaches.

Your hair might also be getting thicker, and your nails could be growing faster.

If you need an amniocentesis for medical reasons, it can be done from 15 weeks.

Your family
It’s common to think about your own parents, the part they played in your life when you were younger and what you’ll be like as a parent. If your family lives far away or someone important to you is no longer alive, you can often feel their absence more strongly when you’re pregnant.

Pregnancy can bring families closer. Some women in particular find they like to spend more time with their mothers or families. Often this is about sharing the joy of being pregnant or the anticipation of a new baby in the family.

Some people choose not to have their families in their lives. You might become very aware of your feelings about difficult past experiences, and pregnancy could bring up strong or painful thoughts and reactions.

If this sounds like you, it’s a good idea to talk with someone you trust or get professional help. You could talk to your midwife, GP or call Lifeline on 131 114. Many hospitals also have mental health workers who can give support and counselling. 

Antenatal appointments are your chance to talk about your health, lifestyle and wellbeing, both physical and emotional. If you’re worried about becoming a parent or there are problems in your relationship, including family violence, it’s a good idea for you to talk about this too. In fact, most antenatal services ask you about domestic violence during pregnancy. This is so you can get support if you need it.

Your baby when you’re 15 weeks pregnant

Your baby is putting on weight rapidly:
  • It measures 9.5 cm from head to bottom, and weighs about 80 gm.
  • Your baby’s body is now growing faster than its head.
  • Your baby might suck its thumb.
  • A fine covering of hair – called lanugo – is starting to cover your baby’s body.
