my girlfirend and i

did u ejaculate in her? if yes.. then there's some risks that she might get pregnant. however, i read that the ovulation period is 14 days before period starts and that sperms live up to 5 days in the vagina. but it is not for sure, different women ovulate at different time.. a pregnancy test is advised if ever she misses her next period..:-)
hope i helped..:-)
