I have not had my period in 2 months since Jan5. I am 25years, got off BC July 06. I took a urine an blood test Feb 16, negative as I was supposed to have my period Feb9. So I figured, I would start in another month around March 16, no period still and negative urine test March 16, 21. I am using OPK and everyday it is always darker or simliar to the test strip since I started using them on March 21. HElp! i cant be fertile for the past week? What gives? Am i pregnant? I have a MD appt on April 3. Have not been doing anything different, I exercise 3x week, not stressed, 120lbs.
