Tummy after D&C

J.
4 weeks ago we found out our baby no longer had a heartbeat at 11wks and had to have a D&C. I have yet to get AF and it seems my belly is actually getting bigger. I look further along than I did when I had the D&C, is this normal? Idk if it's just bloat waiting to get AF or if I should call the doctor. Has anyone else experienced this?
