I have been on birth control since I was 14. My husband and I are trying to get pregnant with our first child, but I haven't gotten my period yet. Im not sure what is wrong with me. My doctor says its normal, because of the length that I was on birth control, my lining is thin, which is why Im not getting my period. Last month I had some spotting but nothing major. This month nothing, I had the normal brown stuff for one day and then nothing happened. My husband and I had unprotected sex once, but I don't know what is going on. I should have my period this week but nothing has come. I am feeling exhausted, I took a pregnancy test and its negative....Any suggestions??
