Not sure what to do.

I have an ob appointment for April 21. At this point, I just want an ultrasound to know everything is okay and to get a head count. I really ONLY want to go for the NT scan and the Quad screen. But I know they are going to give me crap for having another homebirth. I just wish I could just leave it all to fate, but I NEED to know if something is wrong before hand. I hate good surprises, let alone bad ones.
