I know that OBs say it's really accurate...I was just wondering what you all thought. I'm having doubts/questions about my due date of March 1 (which I realize is very much an estimate anyway!). My pregnancy was a surprise and as a result I had zero clue about my LMP (we had been traveling 9 times zones away for over 6 weeks, so I wasn't regular and had been in a big jet-lag fog for a few weeks before my positive test). When I went to the ER to have my IUD removed, they did an u/s that dated me at six weeks, and a blood test that measured HCG levels and put me at 6 weeks, 3 days. We've used the 6 weeks, 3 days to compute my due date. This makes me 39 weeks tomorrow. The only other u/s I had were at 17 weeks (gender/mid-term measurements) and 19 weeks (quick follow-up to a question from the prior one). My uterus is measuring about a week and a half behind, which m/w thinks is a small baby, but this would surprise me b/c my two other boys were very large for their gestation and so I expected another large boy.
I'm kind of going crazy anyway b/c even though I'm only 39 weeks, that's 2 weeks further than I've ever gone before. :) This is the insanity of a mom who's only had preemies and suddenly has a full-term baby and doesn't know how to deal with being so far along! So I'm just looking for ways to keep my brain busy. I've been wondering about the gestational age for the entire pregnancy. Thoughts?
