I am currently 22 days late for my period. I went off of birth control 3 months ago because I didn't like how the birth control made me feel. My first month off I started my period on time...second month I started 8 days late...now this month I am currently 22 days late! I have mild cramping and my nipples are very sensitive. I have taken 3 pregnancy tests and they are all negative. Has anyone had anything like this happen?
