Girls, who had cramps for 5 days before their period, regular cycle of 35 days today evening started pulling at my lower abdomen, but without any discharge. I want to do a test tomorrow, but I'm afraid ? because my husband has poor sperm motility. Fortunately, he went through treatment with a doctor and his indicators improved, and now I wonder if this is it.
