Be band

So I finally broke down & bought a be band this wknd. I also tried on maternity pants from Target, sooooo totally comfy. But I can't afford to pay $30 a pair. Especially needing a few pairs for work. Anywho, back to the be band. I wore it today for the 1st time. It wasn't too tight or too lose, fit kind of perfect. The annoying part is it rolled down a little at the top & slid up from my pants at the bottom. Hopefully that gets better. My only concern is as my belly grows, will the be band support it? Since my bottom half is not growing, I would rather not buy maternity pants. We'll see what happens in a few months. So for now the be band works....
