Hi, I had an unprotected sex with my bf before my period on 11 sep 2016. But when he sensed that he was ejaculating, he ejaculated outside the vagina while we are having sex. And I am scared that even a single sperm entered into vagina may cause pregnancy and so I started eating papayas from the next day. And I got my period on 16th sep 2016 which was late by 2 days. I heard that there is a chance of getting pregnant even after having a period. Is that so? Am I a pregnant now? Can you suggest other ways in which I could make sure about my pregnancy other than consulting a doctor and having a pregnancy test.
