I haven't had my period since the end of July. And I was taking birth control for a couple months and I've always been on time but around late September early October I stopped taking the pill. I've taken 5 pregnancy tests and they all came out negative but I still haven't gotten my period. I've had cramps here and there and sometimes I feel a little bloated I know all the tests came out negative but I'm still worried. I was taking minastrin fe 24 because I was irregular.
