Hello girls, can anyone tell me who knows? After CS it's been two months, yesterday there was an intercourse. After that, I felt like I got sick from inside. I'm afraid that maybe the internal suture came undone? Can this happen? There is no strong pain or bleeding. I plan to go to the doctor soon. Now I'm lying down and it feels like tingling, or aching, or itching from inside, confusing sensations.
