Can i get pregnant from having unprotected sex 7 days before ovulation. i tracked my ovulation and know when my peak day was. he did not cum, but there may have been pre-cum. ive also heard that semen can only live for 5 days in the female body?

An erect penis is secreting sperm continuously during sex, not just at climax. It only takes one getting through to get pregnant. There is no valid way to calculate risk in this exposure. Sexual activity on any day of a woman's cycle can result in pregnancy. If this episode did not get you pregnant, similar sex practices likely will at some point. If it matters get on the pill or use condoms
