I am on the pill and usually do not take every single pill every month because I do not rely on it for sex. It's for acne. I do have sex a couple times a month but always with a condom and it has never broken before and he pulls out even before he goes. But even though I miss just a few pills a month, I ALWAYS start my period on the Wednesday during the sugar pills, since back in July it has been that way and hasn't changed. Well today, I started having small amounts of dark brown discharge, two weeks after my period, and it has now turned into more than a small amount and I have cramps. It looks like and feels like the start of my period but its still dark brown, not red like normal. What in the world is going on?
