Hi, i am 25 and I have always had a 28-30 day cycle. I got my periods on 28th April and had unprotected sex with my husband on 10th and 11th of May, assuming that my ovulation date should have been 6th May and ended maximum by 9th May. However, this month I have not been getting my usual menstrual cramps or weakness in body that I otherwise get from a week to 10 days before my period is due. Also I have been facing high acidity from last 3 days, it was there for the whole day on Friday. Saturday and Sunday it was there only in the morning, and then I feel totally fine later on. Could it be that I am pregnant, when can I take a pregnancy test. But mostly I want to know, how could I have been fertile on 10th May. Or is it something else and not cause of pregnancy ?
