I am 27 and live a healthy lifestyle. I am a lesbian and do not take any contraceptives. I have been having irregular vaginal bleeding for 20 days now. This has never happened before, my period usually is light and lasts at the most 5 days. I started taking Cymbalta about a month ago for depression, and can’t help but think this might be the cause. Has anyone else had this experience with Cymbalta?
