I've been talking levlen ed for 2 years, but recently (3 packs) I've been skipping the white pills to skip my period. It's not week 3 of the 3rd sheet and I've been getting a dark brown discharge for the past 5 days. At one point it looked like a period, and on the first day I had period cramps but it just seems like a dark brown discharge now. Should I be concerned? And will it go away?
