Baby's Development

Your baby is about the size of coming soon.

The Fertile Window — Ovulation is approaching and a tiny follicle is maturing, ready to release an egg. If sperm meets that egg in the next few days, a whole new life begins. Your body is doing everything right, even when you can't feel it.

Your Symptoms

Increased cervical mucus
Mild pelvic twinges (mittelschmerz)
Increased libido

Every pregnancy is different. You may experience all, some, or none of these symptoms — and that's completely normal. If anything concerns you, speak to your midwife.
