Me and my gf got intimate just one day before her expected menses. I didn't ejaculate inside her or anywhere close to her genital, however I am aware of the fact that lubrication may contain sperms. Her menses were expected on 2nd, but is now 6th and yet there are no signs of menses. I have heard that a girl can get pregnant only during her ovulation period and it was more than 25 days since her last period that we got intimate. Which probably clears a fact that she might not be ovulating. Also, we didn't have a complete intercourse, instead, just got physical and there were close contacts with our genitals. Now, should we be worried about her getting pregnant?
