amenorrhea
"During the ten days on Provera I was emotional, my boobs hurt severely, my face broke out like crazy, and I had horrible fatigue. Two days after the 10 days of taking Provera, I have the worst period I have ever had in my entire life. Having to change my pad/ tampon every single hour was disgusting, I couldn't even enjoy a shower because even afterward I still bled non stop. Each day that passes, the heavier my period gets. Today is my 6th day, and 4,5,&6 where heavy as hell, but 5&6 had excruciating cramps. And too many blood clots! :( I do not recommend this pill at all."
