I am currently on Kariva Birth Control. I missed one pill in my second week, and ended up taking two in the same day. I had sex that same day, but it was also protected. However, the next day I had some brown discharge and some blood (about nine days before my period was due). The brown blood and some red blood continued throughout the week. Now, I have still had little blood, varying shades of red, but mainly brown. But now I think that that my cycle has stopped. I am very concerned. I am also being treated for severe depression, have been very stressed, and am taking Celexa and Wellbutrin. I don't know what to think
