i haven't come on my period for 2 months.

you should talk to your doctor sometimes you can not have your period due to stress

i knew a girl who was a virgin who missed hers for 5 months

It is IMPOSSIABLE to be pregnant if you have never had sex or had a boy ejaculate towards the opening of your vagina- Your period could have stopped for a number of reasons but without more info its hard to say. You might want to talk to your doctor but it could be something simple as weight loss, weight gain, a lot of activity as in excersising a lot, Stress, or just one of those things. I do promise that pregnancy isn't the cause if you never even fooled around with a boy. Seeing your doctor would be the best way to get your answer. But if you can't for some reason give me more info about your situation....does any of the reason I wrote pertain to you? Are you taking any medications? Any other changs in your life recently? How long have you had your period? How long have they been "regular" (if at all)? Have you been sick or anything else recently?
Don't worry yourself over this...its probably something simple and easily fixed.

I have the same exact problem under the same exact circumstances. Im sixteen, a virgin, and i haven't had my period in two and a half months. yet i have a very consistent weight (119lbs, 5'3") and i usually have a very regular period, then it just stopped. i haven't had any recent sicknesses nor have i had any traumatic experiences. i'm at a dead end and i have no idea what's wrong, what could it be? thanks

I haven't had my period for 10 weeks. I'm a virgin. I've done oral, but that's it. What's happening?
