Since Sunday I have been having on and off pain in my pelvic area. It is located around where a c-section scar would be. It is a deep burning like pain. It kinda feels like when you have a severe upset stomach or diarrhea. It comes and goes throughout the day but is extremely painful. At first I just thought I had to go to the bathroom but after the first 2 times, I didn't. I have/had endometriosis, and I am about 3-4 weeks pregnant. The pain has woken me up and is excruciating. Could this be related to my pregnancy? Or endo? Could it be constipation related? I've used the restroom every day but on a few days maybe it was less than normal. Something has go lt to give because it is becoming unbearable.
