Okay so this may be a dumb question and I’m sorry about it my sex Ed classes were barley even anything I don’t remember them but so I was grinding on my boyfriends dick 3 days before my period and I had thin thin leggings on and a thong that was barley covering my vagina and he didnt have any clothes on and a couple minutes while I was off his dick there was precum but idk if it was there while I was grinding on him so like could I be pregnant if precum went through my pants like it didn’t feel wet but I was already wet myself so I couldn’t tell and I’m a virgin and I’m just scared we did this 3 days before my period on a Sunday and then my period started on Wednesday in February but I heard that if you do anything sexual before your period that it can start but then not start the next month if your pregnant so someone please help me I’m just afraid that my period for March won’t start because I’m afraid I’m pregnant from that one Sunday in February
