hi, I can't wait to know if I'm really pregnant or not. I'm 30 female from the philippines. My last menstrual period was may 15,2012. I previously took oral contraceptive pills for 12months then stopped last may. Since then,I had unprotected sex,but my last unprotected sex was 2 weeks ago.. right now, my menstruation is still delayed. In my calculation, I'm 7 weeks delayed already.and yet, my home pregnancy test resulted negative. I've done pregnancy tests for 4x already with 2 days apart.my questions are:1. I'm I really pregnant? 2.would using ocp for a year affect my ovulation? 3.if I'm not pregnant, what can be the possible cause of my delayed menstraution? Hope you will send me insights on my problem.tnx very much. Tnx a lot
