I'm on the trinessa (norgestimate and ethinyl estradiol) b.c. (generic for ortho tricyclen). having light spotting and brown discharge a week before period. are they still working?

It sounds like: You need a different pill if this is a persistent issue. It's likely due to lower estrogen at the end. A 35 mcg pill that doesn't change in doses, mono phasic, is good, may consider Necon 1/35. There are other things that can cause this like cervical inflammation but lets assume it's the pill, call your doc. They are still covering u unless u r on one of a few drugs that decrease hormone levels.
