Yep - this. Originally, we said we didn't want to find out, and were even on the fence about having any ultrasounds at all. Now we've decided on the one 20-week ultrasound. My husband said he wanted to find out, but he would keep it a secret from me . . . no way that would work!! I would weasel it out of him in hours. BUT, I don't want to tell anyone else. It will be our secret. That way we avoid the clothing purchases, and I've found it keeps people from criticizing your name choices, since the natural line of questioning seemed to be: What sex? What name? - at least in my first pregnancy.
I am having some trouble still believing this baby is real - despite being 17 weeks tomorrow and feeling movement, and an incredibly strong heartbeat at the midwife last week. So, an ultrasound will really help me, I think, in connecting with the new baby.
