7 Weeks Pregnant

Settling in

This week your baby is around the size of a blueberry.

How your baby is developing

  • Lots of early development is happening, even if your body looks the same.
  • Limbs and facial features are slowly forming.

What may be happening in your body

  • New likes and dislikes for food and drink can appear around now.
  • Your blood volume is up to 50% higher than usual, so you may feel thirstier.
  • Drinking around 8 medium glasses of fluid a day helps with the extra thirst.

How you may be feeling

  • It's common to swing between excitement about the pregnancy and sheer exhaustion within the same day.
  • Some people feel a quiet guilt for not feeling more glowing while they're this wiped out.
  • On the heaviest days, it can help to remember you're managing far more than shows on the outside.

Worth remembering

However these weeks are going, they are the ones you are in.

A closer look

The invisible workload of week seven

Even though your body may look no different, a lot of development is underway: the brain is generating around 100 new brain cells every minute, and the limb buds are forming cartilage. Your own blood volume is up to 50% higher than usual, which is part of why you may be thirstier than before.

Something you can do this week
