okay, so i had sex November 17 and it was during the first day of my ovulation, i started my period on November 8 and i got off on the 15th and had sex on the 17th. i have been experiencing some symptons and thats just my boobs are real tender and my nipples change to a darker color. i have also experienced a little bit of bleeding but i know its not my period because i had already had one that month and im not due for my next period until December 6th. I was thinking maybe its implantation bleeding because usually when a female has implantation bleeding a week before your next period and i started bleeding last week on November 31, the week before im suppose to start. does it pretty much sound like im pregnant?
