You’re officially halfway through your pregnancy now.

At 20 weeks pregnant, you’re now half way to your estimated due date.

Baby is growing bigger and gaining more weight each day. They’ve doubled in size over the past three weeksnow measuring in at around 16cm from crown to rump. Their hair and nails continue to grow and the vernix is thickening too.

Due to their increased blood volume and enlarged uterus impacting blood flow, some pregnant people develop varicose veins. Your belly button might also start poking out as your bump grows – the amniotic sac has around 400ml of fluid surrounding the baby.
