I've been having a brown discharge since around may 20th. and i haven't had a period since then. i was wondering if maybe i'm just not releasing eggs?

GYN: Get an evaluation for the discharge and take it from there.If you need further testing,your doctor will let you know

Pregnancy test?: I assume you've checked pregnancy tests? If they are negative then anovulation is a possibility. See your GYN for evaluation.

Difficult to say: At your age, if your weight, activity and general health is normal, missing your period for 2 months should be concerning. Discharge? requires examination now. Get going.
