Hi, my wife had delivered 5 months back, since then she didn t have normal menses , we assume that it is bcoz she Brest feeds a baby. But every time we do an intercourse, she starts to bleed, and feels a lot of pain in the utrous, we went to the doctor last week and she found deep inside vagina some blood clots as well as a hard skin red coloured which looked like a blood clot but wasn t, it is sent to lab for tests, do u know what might that be. ?
