Hey guys so last month my boyfriend ejaculated on me and even if i was wearing clothes so i was afraid to get pregnant so i took a pill that is usually taken to stop ovulation or make it late and after that i guess i got my period but it was weird it wasn't like usual so i waited for 23 days after the night when it did happen to make a urine test i've made 2 of theme and they were negative but this month i am waiting for my period and it's late. Do you think that i have any chance to be pregnant?
