I'm 9 weeks and 5 days pregnant, and I had my booking in appointment and an early scan last week. I just had a phone call from my doctors saying the GP wants an extra urine sample from me next week but the receptionist wasn't sure why. Any ideas why this could be? I had a late miscarriage at 21 weeks last year so I've been an absolute nervous wreck since I found out I was pregnant, and this has really worried me!
