The official point of the ultrasound was to check and make sure that the placenta wasn't covering the cervix. The good news is that I have a clean bill of health on that front.
The unofficial thing I wanted out of the ultrasound was to get confirmation on the whole gender issue. My Ravelry queue is full of adorable little girl things, but I am loath to knit any more of them until we are more sure, lest I end up with a little boy and half a dozen dresses. Sadly, the baby was decidedly uncooperative on that front this morning. We got a good look at important stuff like the brain, heart, spine, etc., but no genitals were on display. The fetus was breech and facing my back with his/her legs firmly closed, the worst possible position for getting a gender shot. The fetal butt is apparently right on my bladder, which would explain why I have to run to the restroom every half an hour. So, we have gone from being told a girl is a pretty sure thing to being told to keep the receipts for the pink stuff. I guess we have no choice but to be totally retro and not find out for sure until we're in a position to put on the first diaper.
My Mom is convinced that this news means that I am having a little boy, especially since I did "jinx" myself by knitting a dress. Mom knit a little boy's outfit when she was pregnant with me only to have both her kids turn out to be girls. Of course I suspect Mom wants me to have a little boy so I can give it the boy name that she had all picked out, but that just isn't going to happen no matter how much she lobbies for it.
I'm a little concerned about the fetus being breech. In theory they don't get worried about this until 35-36 weeks. I might have to ask my OB how she feels about a vaginal breech birth, since I really, really don't want a C-section unless there is no other way. Still, it is officially still to early to get worried about this now.
