Found out last week I am pregnant with baby number 2. I'm approx 5 weeks. A very planned baby, my DS is 20 months and an excellent little boy. It hasn't really sunk in yet - although seen doctor & booked midwife appointment. I can't shake how scared I feel & just want these weeks to go so I can finally see our baby on the scan. I don't remember feeling this on edge with my DS...is this normal or am I just being silly?
