c section mommies.

I'm 4 weeks post partum. and my incision for the most part had done better. 2 nights ago Sebastian and I had sex, so all day yesterday I've had this sore pain. it's like right around my ovary area on the right side. before anyone freaks out. my ob says having sex as long as I've stopped bleeding and using protection is perfectly fine before 6 weeks post partum. could it be that I probably engaged more muscle work than normally or should I see if it carries on for another day go to the Dr?

has anyone else gone through the soreness part suddenly after your pain went away after the surgery?
