How to "Hide" Third Pregnancy... for a while at least

Ai
Moms, how did you do it?!
I'm 5w3d with Baby #3 and "showed" (yes, the bloat) early even with my first. The teeny tiny baby and bloat aren't easy to hide as I am 5'8" and 120#'s.
So keeping the pregnancy on the down low until week 12-ish... any suggestions? (Besides wearing sweatshirts every day!) 
Or anyone in the same boat at least?!
