I keep having a worry that at my next ultrasound they'll tell me I'm having a boy even though I'm having a girl. Only reason I'm worried is because the gender ultrasound I had we could only really get one decent picture of what the baby might be and I've already got all kinds of girl stuff. For people having a girl could you post your ultrasounds?
