I am on Depo Provera , I have had 2 shots so far...last saturday my husband and I had unprotected sex and the next morning, after I wiped, I had light pink blood on the toilet paper. Since then I have had brown discharge after urinating. Im worried I am pregnant, although I did take a test my 2nd month on Depo because my husband and I had unprotected sex 2 weeks after my shot, the test was negative. Are these symptoms normal on Depo or should I take a test and schedule and appt with my doctor?
