Could be pregnant at 18


So basically last Friday I had sex with my boyfriend and he used a condom and pulled out before he came we checked for holes and nothing. I was suppose to have my period yesterday and I’m kinda freaking out and today I felt my underwear wet so I went to check if I got my period and it was just a lot of discharge so idk what to do?? Could I be pregnant or am I just over thinking? Btw I have very bad anxiety so I over think a lot so I wouldn’t be surprised if y’all think I’m crazy 🥺
