I've been on the highest dose of Gildess for 10 months and these last two months, I've had cramping throughout the cycle and brown discharge/ spotting the week before I'm supposed to get my period. I take my pill every day and on time, so what's up? Last month I didn't have my period and I'm thinking it's going to happen this month (which would be two months without a regular period).

*I did take doxycycline for one month, but stopped because I heard/read it interferes with your cycle if you're on birth control.

HELP.

-I'm about to turn 21
-I don't smoke or do drugs
-I haven't gained weight since I started the pill (I lost like 5-10 pounds)
-I guess I'm sexually active (oral sex, mutual masturbation)
