I'm certain as well, I get distinctive ovulation pain, and I have a really regular 28 day cycle. I ovulated that month on day 15 instead of 14, so I am maybe really 41wks tomorrow, but its *damn* close!!
though I do feel like I am behind, size-wise at least. My belly has been pretty small looking all throughout this pregnancy, though I guess I measured fine. I also even did get bigger this last week, which seemed odd since I thought from 40 to 41 the babe wouldn't gain much more? I do have a LOT of amniotic fluid evidently as well though.
It might be that I just can hide a babe well though and there's a soon-to-be-10lber in there.
I'm not sure which is worse, having the prelabor or not. I had it at 38wks, then nothing, until yesterday, and I guess I did have a lot of cramping and contractions last night which gave me some hope, but then it waned by the AM. In some ways it was nice to feel 'close' again, but then the disappointment sucks! and knowing that I had it at 38 and nothing for two weeks doesn't make it feel that close anymore.
Since I don't know what actual labor is like yet either its distracting - I get cramps, and contractions, but they don't seem to happen at the same time or in any pattern w/ each other, its odd. And its easier to tell the frequency of the cramps rather than the contractions since my belly feels so tight sometimes its hard to tell if I *am* having a contraction while I'm feeling the cramps.
that came out much more confusing than I thought it would, but its usually the middle of the night that I am trying to figure this stuff out so its possible its not *that* confusing and I'm just too sleepy to tell what's really going on!
I did have a lot of cervix pressure today when walking so hoping the babe is doing *some* work down there at least.
