I'm 18have a regular cycle. i'm sexually active. i stated bleeding today a week before my period out of the blue no symptoms and it stopped. pregnant?

Pregnant?: You state you are sexually active but don't say what form of birth control you are using. That being said no birth control method is 100% safe except abstinence. I would suggest you get a pregnancy test and repeat it several weeks down the road. Good luck.

Probably not: pregnant and bleeding caused by hormonal disorder or cervicitis or trauma to vagina or cervix. If this happens again see your gyn. Take a pregnancy test if you miss your period.
