Boobs and Running

You all know those cute colorful sports bras at Target?  I now understand how lucky I’ve been to be able to throw one of these on and go for a jog. I realized this week, at 17.5 weeks prego, that I am in need of more support. Running this week I had burning pain and wanted to hold my chest to keep them from bouncing. Some of you have told me that wearing two at once for extra support can help. I might try that first, but I know I need something. 

Watching a DVR’d episode of Shark Tank I saw a very timely presentation for the Shefit sports bra!  Looks interesting, but expensive. Has anyone tried this?  How about those of you with more experience?  Any recommendations?
