"i am 20 years old and i have been on this for over a year now. i tried other birth control pills before this one, but the estrogen levels were way too high (my boobs got bigger and i got extremely moody). lo-loestrin was so much better! since it has such a small dose of both hormones, i haven&#039;t noticed any negative side effects. the first couple of months i had dark, sticky discharge (especially during menstration time); however, since then i have not had a period. my gynecologist says this is okay at my age and not something to worry about. overall i am very happy with this birth control."
