Many options : There are so many birth-control pill options on the market this particular brand you are using may just be too low of a dose. Consider trying another brand or another method.

Call your gyn: Loloestrin is a pill i prescibe a lot, sometimes u can have some break thru bleeding for 1-2 months but it should not be heavy and the lolo sholdl make your period much lighter or none, if u have not had an ultrasound your gyn should do an exam and ultrasound.
