My weight shifted and there was some bloat early on, despite an 8lb loss by 7/8 weeks. The belly came and went and came back again. I'm now 15 weeks + and definitely require the maternity wear. Last week I noticed some deflation, though, lol. It's very confusing and sometimes alarming, but being I *just* had my ultrasound last week and baby measured ahead, I know all is well. Oh, and my OB told me the natural progesterone increases in pregnancy slow down one's disgestion causing quite a bit of bloat - are you still on progesterone supplements? Could be that, too. I find Zofran causes the same bloat, as well.
