I had my period this morning!? Its the first time?!

It's different for every girl. Some girls have it for 4,5,6 days but usually its betweeen 4-6 days. I ont know why your feelings dizzy, but its probably your body's reaction to this new thing.

Cindy,first I'd say welcome to womanhood. Good u know what to do. As for the dizziness, maybe that's how u react to it. Your body is bound to change. Observe all the signs girl. All the best

It can last between 4 to 7 days, and varies between individuals... I guess you're feeling dizzy because you are losing blood. But if you persistently feel dizzy, seek medical help!

Anywhere from 3-7 days.

I always feel dizzy when I get my period, you just have to stand up slowly. If you jump up, you might pass out.

I Havnt started yet and im 14 but welcome to mother hood! congrats..should be nothing to wory about it'll only last a couple of days :)
