I'm so glad I asked!! Whew, so it is normal and doesn't necessarily mean anything is wrong.
No, I'm not heavy--I haven't weighed myself since before I was pregnant but probably 135 lbs? The midwife really tried for a long time, too. I thought she was so patient, tried lots of goop, lots of different angles... she just said that my uterus is still in my pelvis and baby could have been all the way at the bottom or back.
I feel guilty about this, but... part of the reason I can't stand the idea of losing the baby now is that this trimester has been so incredibly miserable--I don't know if I could ever stand to go through it again. And I don't want to feel like I went through it all for nothing.
Ugh, I know so many of us are going through that and it just breaks my heart. No one should have to go through morning sickness without getting a baby in their arms at the end of it all!
