Abdominal Soreness Returned?

AutumnLeaves2

I had my c-section 5 weeks ago and my body seemed to have bounced back from it rather quickly (I was out of the hospital 2 days after my delivery and after the 1st week I had no soreness at all)

But over the weekend I noticed that my lower stomach was extremely achey, felt filled with gas (like it did immediately after the surgery) and feels sore to press on. It's not my incision that hurts, it's internal like stomach muscles.

Did I just do too much too soon? Or should I call my OB? TIA!!!
