I had my period on 8th nov and ovulation on the 23rd. i had unprotected sex on the same day. i started having cramps six days later. what are the chances that i'm pregnant?

Pregnant: High. You had exposure to semen when your egg was most ready.

Decent : Having sex around the time of ovulation is the right way to do it if you are trying to get pregnant. The odds in any one cycle are around 20%. Check a pregnancy test if you miss your next period.

Cramps 6 days out: Is not really an indicator for pregnancy. Having unprotectd sex at the time of ovulation certainly increases your chances. You can take an early pregnancy test up to 6 day prior to your anticipated period or a regular pregnancy test if you miss your period. Good luck.
