I had sex a couple weeks ago. I am on kariva birth control and take it everyday. We also used a condom. Last month for seemingly no reason I had my period for two weeks so I don't know what to expect this month. Today I had some brown red discharge. I've had random discharge before but don't know if I should be concerned. I'm also on antidepressants for severe depression. And under a lot of stress right now. I'm just hoping I get my period next week.
