Me & my fiace had unprotected sex the day before ovulation then unprotected sex the next day on ovulation day. chances of getting pregnant are?

Depends on testing: If your fiance has normal sperm and your fallopian tubes are open, and there are no other issues, then at your age the chance of pregnancy is quite high... Perhaps 35-40%. But if there are other issues such as those mentioned, the rates could be very low. Best to see a fertility specialist if you have tried like that for > 6 months.
