Please see pic, I have a large dent in the middle of my tummy around my belly button. I’ve always assumed it’s diastasis recti from my last pregnancy (4 years ago) I’ve mentioned it to gp in the past and it’s been brushed aside (never been to gp specifically about it but I’ve brought it up in appointment. Looking online though it suggests diastasia recti is more of a protruding bulge than like what I’ve got. It’s really getting me down, and I have terrible lower back ache too. Just looking for opinions. I accept it could be down to carrying some extra weight, I’m a size twelve and not exactly toned.
