My first and only ultrasound was at 8 weeks, I didn't get one and 12 weeks, and I've got my 20 week coming up on wednesday (at 19 weeks)! Was anyone nervous going into it? I've opted not to have any tests done for DS and spinabifida, but I know they check for markers at the U/S so now I'm starting to get nervous. I have no reason not to believe baby is healthy and happy and growing away, but it just hit me all of a sudden that its not always the case and now I'm a nervous wreck!! I've been looking forward to finding out the sex for so long that it never even occured to me that I'd be nervous too!! Anyone else feel this way before their U/S?
