I mentioned in my CVS post that my uterus is apparently (very) retroverted, so they couldn't do the procedure yesterday. I know this supposedly is the case with 20-25% of women and isn't a big deal. However, from the poking around I've been doing, it looks like it was supposed to tip forward around 12 weeks, which hasn't happened yet (I was 13 weeks yesterday, but baby measured 13 +4 on ultrasound.) Did anyone else have a retroverted uterus? When did yours tip forward? Hoping that mine will do it soon so that I can have my amnio in a few weeks, since the CVS was a no go.
