I went through stages where one day I looked 30 weeks pregnant and the next I'd look 8 weeks. It just depended on how bloated or backed up I was I suppose...lol (sorry tmi).
But there did come a time when I did pop and my baby belly was noticable all the time....I can't remember now what week I was.
But even now, it seems like I look soooooo much bigger in the late afternoon/evening that I do in the morning/early afternoon. It's like every night I bloat up terribly.
My daughters teacher is pregnant. I found out about a week or so ago when she was around 13 weeks. But she most definately POPPED at 14 weeks. There's no questioning it now. It suprised her as well. She practically popped over night.
