Pregnancy week by week


At 13 weeks, your baby is about the size of a peach

What happens when you are 13 weeks pregnant?

Your Baby

Your baby's brain is developing quickly, and each day new nerves are growing and connecting around the body. The face is becoming more recognisably human, with the eyes moving together on the front of the head, and tiny eyelashes and eyebrows beginning to appear.

Mum and Dad

This is the end of the first trimester, the first third of pregnancy. At this stage your risk of miscarriage drops greatly, so if you haven't already told friends and family about your pregnancy at 13 weeks, you might want to start doing so now. Most mums find that sickness and tiredness start going away around now, and they can start enjoying their pregnancy.

Stay Healthy

As sickness and tiredness fade, you may be feeling more energetic. Keep active throughout your pregnancy with some gentle exercise such as swimming or walking. It's worth looking into special antenatal exercise classes - contact your local gym or council leisure services to find out what's on offer. If you haven't already started, practise your pelvic floor exercises, to strengthen the muscles you use when you urinate - this helps to prevent stress incontinence after pregnancy.
