I fooled around with this guy I know a few weeks ago and now I think my period is late and I'm worried about being pregnant and I can't go to the doctor because then my mom will find out. What should I do? Please help

Depends on what you mean by "fooling around". If there was penile insertion or any chance that semen came in contact with your vagina, then pregnancy is possible.

Scott the thing is I don't know if semen came in contact with my vagina and I'm really scared I might be pregnant and I don't know what to do.

How late are you? You should be absolutely sure you missed and then take a EPT.

But if there was penile insertion, there was likely some level of ejaculate.

I'm not exactly sure how late I am but I'm buying a test today and hopefully it will be negative.
