hi, i was on the third day of my period, when me and my boyfriend were messing around. we didnt have sex, and i did have my underwear and a sanitary towel on, but my boyfriends penis was pressed againt my underwear near my vagina . although he did not ejaculate i know there was some pre ejaculation . after this i went to the pharmacy and she gave me six femiplan pills to take. i took these but im still worried about pregnancy
