Diastasis Recti?

As my belly has grown I have noticed when I lean back my belly does something strange...the midline straight down my stomach sticks out (only when I lean back), did some research an stumbled across diastasis recti, do you ladies think I may have this?

Yes, I know you guys aren't doctors and I plan to ask my OB about this at my next appointment but wanted you guys opinion.. Thanks in advance!
