Hello ?, I wanted to ask, who had this experience? Today I went for a check-up with my doctor, sat on the chair for examination, looked at her and fiddled around. She said my head was lowered, after which I started crying, strong pains began as if during menstruation (she told the doctor that it's normal, etc.), then I came home and noticed brown discharge, an hour later they were bloody, my stomach hurt, it would loosen up… This has been going on for four hours now (my lower back and stomach hurt like during menstruation… What could it be? Are these practice contractions? Or real contractions? Or did she damage something there?
