Answer
Hi Corrina,
Don't worry. You can only get pregnent from sexual intercourse, not from rubbing up against someone. You may want to keep track of your periods on a calendar. This is a good idea because sometimes women have irregular periods, and this is something to talk to a doctor about. You may want to talk to your mom about sex, pregnency, etc just so you have more information. If you aren't comfortable talking to your mom, ask your doctor fo more information next time you see her/him.
