Week 20

This is the halfway point of the average pregnancy. You might have an ultrasound scan this week.

Your uterus is taking up a lot more room, and some of your other organs – for example, your heart and lungs – now have less space. You might feel a bit breathless at times, especially when lying flat on your back.

When you’re lying down at night, you might need to put a pillow on one or both sides, or even between your legs. Many women find this helps ease the feeling of aching hips.


New grandchildren can often make family relationships stronger and closer, but not always.

The relationship between grandparents and grandchildren can have a very positive influence on children’s development. Many grandparents are amazed and delighted at the joy, fun and love that becoming ‘nan’ or ‘pop’ can bring to their lives.

Your parents and your partner’s parents might like to read more about becoming a grandparent.
