Never thought my pants wouldn't button at just 9.5 weeks! Bella Band?

I'm officially sporting the rubber-banded pants for the first time today.  I know I'm not showing as of yet, and this is mostly bloat (and likely because I am (was) thin as a rail before getting preggers) but my dress/work pants are already not fitting. 

Before I run off this weekend and start buying maternity pants, has anyone used the Bella Band? Will it hold me over a bit longer before splurging on a new wardrobe? 

Thanks!
