How to get pregnant?: Yes. If his penis was inside of your vagina on an ovulation day then you can get pregnant. Remember there is a phenomenon of pre-cum. This is semen and sperm that leak from an erect penis. Pre-cum is just like ejaculation when it comes to pregnancy.

Yes: Regardless of whether he ejaculated inside you or not, if you engage in unprotected sex, you can get pregnant (and catch sexually transmitted infections). If you miss your period, take a home pregnancy test (precum contains sperm, too). If test is negative & you don't want to get pregnant, go see your doctor to discuss contraceptive options. Then make him wear a condom every time to lower sti risk.
