had unprotected sex dec 15 and got my period dec 21
i didn't hear a question..but by looking at ur age...congrats? (on the period). it means no pregnancy.
trick:
take UR average cycle.
From the start of your first day bleeding subtract 14 days. this is the day of ovulation. egg released ready to meet sperm happens on this day . eegg last 1-3 days. sperm last 3-5 sometimes 7 days. Counting first day of bleeding as day one. findout what day u had sex.. addd 3-5 days and see if any days had a sperm and egg appearing together at the sametime. this is whe window of fertility.
