30 Year Old with 2 kids just got my MM!

Noticed tonight I had some blood on my gauze. Underneath my right breast it looks like the wound has opened? I am going to call my dr in the morning but is there anything I can do? Will it need to be restitched?? Anybody else have this before? I am two weeks out from TT, BA and BL.

I wear this Velcro binder. Nothing fancy but gives me great support bc it's adjustable. Sorry about the blood on it! Just found out I can wash it lol. The bandage I have is actually one of those adult pads and I cut it in half. The top goes underneath my breasts and the bottoms covers my scar. A huge pack of those are $6 at the dollar store!
