I got my period last june 14, I had an unprotected sex last june 27 (im not sure if it is unprotected since I am still wearing undies and he was naked while rubbing his penis on me) he didnt ejaculate but I am afraid of the pre cm . July 9, about 7pm I had bleeding which lasted about 7 days. I experienced abdominal pain and moderate - heavy blood flow on the first 2 days and PMS. The color was actually dark red and as the bleeding continuous it became bright red and on the remaining 2 days, I got browish blood residue. 9 days after my period, I had a Home Urine PT test and it turned out to be negative. Should I still worry? Please help me. I have read some posts and articles that you can still have period while you are pregnant.So please help me. Please
