So I was dumb enough to engage in unprotected sex while my girlfriend was on her period. I really don't know if I leaked precum or not, but it seems likely according to the other posts. I was not close to ejaculating during the intercourse. After this, she discharged a large amount of blood from her cycle. I have masturbated about 27 hours, so most likely if I precummed, there would be trace amounts of sperm. This is one day after we did this, and as of yet, she doesn't have nausea in the morning or after eating, and her breasts are not swollen and/or tender. What are the chances guys? Can you get pregnant from precum?
