I did make it through my first trimester with out wearing maternity clothes.
A week ago Tuesday, I had my clothes (non maternity) took Hunter to his Mother's Day Out and went to Sam's. I kid you not that while I was walking around Sam's I had to loosen my belt!!!
From that day on I had to do the maternity pants. However, because I don't really have a well shaped belly My maternity pants will not stay up themselves so I am using a belly band. It it working out okay.
Now, the down side is that even though I can still wear my non maternity tops, most of them do not cover the bands on the pants... Now, I know this is all trivial but the end result is that I actually just look heavier than I am and not really pregnant. I know I know - quite your bitching!
