Sooo, after reminding myself of numerous overlooked details, I have decided we have been quite off on our dates.
For 1 thing, much later baby movements than my first 2 pregnancies. Not too unusual since every pregnancy is different, but I am very small framed and was quite surprised to go a full4-5 wks longer w/o movement.
Really quite unsure of conception. For sure had a period in Sept, *maybe* one in Oct. We went by the Sept date since that is what I was measuring closest to, but I wasn't at all sure how long my cycles were, and DS was still nursing so they could have been affected by that.
I quit seeing our MW after about 15 wks, went to an OB 1x, and measured 'right on' for my Sept period dates. But that isn't necessarily right since I'm a 3rd timer. I could measure a few weeks ahead and still be normal. (never had an US)
Sooo, this, combined with a few other factors, lead us to believe that I am a few weeks off. Possibly just approaching 40w. I cannot believe how uncomfortable I've been and am not even as far along as I thought! Any ideas how to tell the gobs of people waiting on a birth announcement that they have a while to wait?
As someone who is currently 41+4, I can sympathize! I hope it is soon for you. Being a long gestator is exhausting!
