I'm weighing 160 at 4wks 5days but I'm very bloated and constipated and can tell that nearly 6lbs of it is from the problems I've been having.

I was 114 lbs pre-pregnancy and am 120 lbs at 14 weeks pregnant, my doctors say I am in a normal weight range for my height and such. Still a long way to go!

34 Wks 1 Day. I'm 169 lbs...just got down to 128 lbs when I found out I was pregnant. I hope I don't gain too much more.
