I have never ever missed a pill and take it at the exact same time every single day- give or take a few minutes and that's it. I also use a condom everytime still. First it was brown discharge so I figured I was spotting because it happened the last 2 months as well but now it's my period and I'm on my last week of active pills. What's going on, should I be worried? This is also only my third month on the pill (necon 1/35)
