Hello! So, A Little Background Information. I Have Recently Stopped

Hello! So, a little background information. I have recently stopped taking prozac (20mg) that I have been on for four years, and I have been on birth control (necon 7/7/7) for a year. It's about 9 days away from my period and I am experiencing an itchy vagina and now kind of a chunky discharge stained with light blood. A few or so before the bloody discharge I have had yellow discharge. I frequently use a vaginal deodorant. I am so sexually active but I have not missed a pill ever and am very on time. I am beyond worried. Could this indicate pregnant or an infection?
