I am having the worst time getting maternity pants (jeans, capris, shorts) to fit properly and comfortably. MY issue is that they just don't stay up on me. Perhaps it is because my belly is not big enough yet?? I am buying my normal size (pre-pregnancy, depending on what the brand recommends. When I wear them (any brand for that matter) I am constantly finding myself pulling them up. I only wear the full panel kind (not underbelly bands) Maybe that is my problem???
