I think I have started my period but there is a lot of blood?

Are you talking about just starting your period for this month or just starting it as in life your first one??

Some women have extremely heavy menstrual flow, others dont. I am not a doctor!! if you are sexually active there could be other problems. If you are experiencing sharp abdominal pains you should probably talk to a doctor. But if you just feel like crap and are irritable and your body is sore and stuff, welcome to being a woman, glad I’m not one. Have you or can you talk to your mother about this, if not her then the school nurse or guidance counselor? you need to get some pads or tampons so you wont destroy all your clothing. I wouldn’t worry too much I think it scares the hell out of every girl when she first starts to menstruate.

Starting as in my first one

Thats exactly what happened to me when I got my first period its normal as the kid at the top said welcome to woman hood later after you have more your boobs will hurt and get really bad cramps its just the beginning. but not to worrie just ask your mom for help she will be more than willing to give you advice. hahah it couldn be that bad I balled the first time I had mine.
