yes, your body is still chaging through your teenage years. If you have had unprootected sex and the bleeding is not like a normal period and is spotting then it could be implantion bleeding. I hope this helps

Yes, you can get your period two weeks after just getting one. Bleeding is NOT a sign of pregnancy in normal cases.

yes

its possible and quite common actually

like eiri said bleedinf is really NOT a sign of pregnancy. a very very small percentage of women ever bleed during pregnancy

I wouldn't call it common ! I would have to say that breakthrough bleeding is normal at your age and it is caused by hormones. It is not a period perse.

not necessary very common but does happen... or to not get it at all for a while.. like in highshool i played heavy sports and would miss my period alot

have you by any chance taken plan b recently? moved in with other women?

It is not common for a period to occur only 2 weeks after the last, however, it is generally not cause for panic.

Maybe if things continue to act out of your normal range you should see a doctor? I'm sure nothing is wrong, but it certainly couldn't hurt.
