I started taking the monistat 7 day treatment for a yeast infection. i'm now experiencing pinkish gooey discharge. is that normal?

No, not normal: This suggests your apparent yeast infection might have been something else; or you had both yeast plus another infection. Any new, abnormal, or unexplained vaginal discharge should be professionally evaluated. Colored discharge suggests infection, and STDs (chlamydia, gonorrhea, etc) are a concern if at risk, e.g. new or unsafe partner. See your doctor soon. Good luck!
