Missed my period and I can't be pregnant

Before you guys say somethin...I am a virgin so I did not get pregnant and that is not why I missed it but can you tell me what you think may be the problem cause I didn't have it last month...

I don't know how old you are, but I do know that the first few years or so your period is pretty irregular. I've had mine for almost two years now, and I still sometimes get twice a month or a month without.

If you're a teenager, you really probably have nothing to worry about.

Do you have an eating disorder?

THAT WAS A SERIOUS QUESTION.

Eating disorders CAN cause abnormalities in the female menstral cycle.

Captainassassin is correct.
Eating disorders CAN do that. (Also stress, excessive obesity and some drugs.)
But the most common thing is simple variation in the cycle.

Also if you have just started a sport or anything like that it can make your period very light or possibly make it just go away.

I don't know...it happens to all teen girls I am guessing! There is nothing to worry about
