I've never made it longer than 39 weeks so to me, 13 weeks is at least 1/3
but I've got a ways to go yet. I feel so far behind on this board and so far ahead on July! I'd really be shocked if I make it to July, though. I've never made it to the right month, even when I was due on the 17th, I went the 28th of the month before!
So I just go with 14 weeks and then I know I'm done with the first one. I usually stay pretty nauseous until about 18 wks anyway so it doesn't really mean much to me. Boo!!
Personally, I love the 20 week milestone b/c pregnancy always seems to fly for me after that point. Admittedly though, I've never even approached an EDD without already having a baby that is multiple weeks old. I bet time stands still those last few weeks if you have to go the full term.
Oh yeah, I don't even want to hear complaining come June when people don't have babies by 39 weeks and start to get grumpy My boys were 10 and 11 days late. It is NOT fun to go overdue! Just watch, I won't have this one until over half of you guys already have yours, and my DD is the 1st!
I was 40+3 the first time, and although it's uncomfortable and sucks waiting, I would like to be 40 weeks again. I'm calling 14weeks the second trimester because I still feel like such garbage, and I am determined to feel better this time around by the second trimester. So I have until Saturday to get my (some please ) energy back.
