Stomach pains

I need a little bit of help. I just had my second baby 3 months ago via c section. Well of course major abdominal surgery, so stomach is expected to be sore. Well here I am 3 months later and still have a little bit of stomach and back pain. Plus my stomach hasn't went down like it did with my first. Still look about 4 months pregnant. Idk what to do. I know I should possibly go to the doctor, but I just want to know if any of you ladies experienced anything like this.

By the way, I had one cycle at 5 weeks postpartum. Light and lasted barely 3 days. Haven't had one since.
