This is the second month I have gone without getting my period. I am 25, have not had a weight gane, not under a lot of stress and I am on the pill. I have never had this problem in 10 years of being on the pill and my nurse told me if the test is negative and I got my period the month before that I can't be pregnant and to start my normal pack of pills. Now this is the second month of not getting my period what is going on?
