I Have a stupid question. But im worry so much. Please somebody tell me something. I was fooling around with my gf. And she was wearing an underwear( Heavy petting ). But now she's late on her period. It's been 10 days more i guess. She not having perios at november. And now is december 10. She never get period at the same time every month, sometimes in middle on month and sometimes in the end of month. Im worry so much about this. She is 18 and im 20. I remember that I didnt cuum at all. My question is 1. Is there any chances if she get pregnant right now? 2. Can sperm(pre-cuum) go through underwear? Cuz i dont remember if she 'wet' or not. 3. Is the girl under 20 normal to have late period like this?
