When you first start your period is it normal to have light 1 and a half to 2 week long periods that average 19 to 22 days apart?

Periods fluctuate a lot at the get-go, but it's still in your best interest to talk to a gynecologist. Furthermore, now is a GREAT time to look into finding "your" gynecologist. These doctors are important, and you need one you feel comfy with.

She can tell you what's best to do, what to expect, and give you good advice on regulating periods.
