birth control
"I am 18 now and I have been taking this pill for 2 years now. Since I started taking it my periods, which were already normal to begin with, have significantly decreased. Now my periods last from 2 days to sometimes not at all. It's scary but reading some other reviews I find that this is common. I never had nausea, but I did have some increase in acne. This is still a good pill but I wish I would have a DEFINITE period each month."
