Hi. I need some help. My boyfriend and I had unprotected sex last Jan. 2 and 3. Then, Jan.9, I had discharges, brown in color. And I don't think that was my regular period. My last LMP was Dec.12. I was wondering if that was an implantation bleeding? It was a light discharges and lasted for a week. I told it to my boyfriend but he doesn't mind it coz we think it was just a period. And now, I was worried because I haven't got my period for this month of February. We had a sex again last Feb11. Am I pregnant? But i haven't feel any symptoms of being pregnant. I'm so worried. Can someone help me? I have abdominal cramping now, and my breast is painful when i touch it. Is there still possibility that i will have period or is this a symptoms of pregnancy? I'm still expecting to have a period coz i don't want to be pregnant yet. Can you please answer my questions? please.. ASAP..
