Diastasis Recti

Serenity
Anyone diagnosed with Diastasis Recti after baby was born? If so, what exercises are you using to help close your gap? I am newly post-partum with baby #2 ( 4 weeks pp) and my condition seems to have gotten worse. My stomach does not sink in but rather bulges out. I have an open naval Diastasis Recti, anyone else experiencing the same thig?
