I have been on the depo shot for going on 4 years now, I have always really liked the convenience and have never had a problem, until recently.
Quickly after receiving the shot I stopped having periods all together. And haven't had my period once at all in the last 4 years. I started to have extremely painful cramping, and suddenly I was bleeding. It's become a constant all night and day thing for two days straight now, I am not due for my shot for 2 weeks. I can't imagine it already being out of my system after taking it for these many years, my biggest worry is that I did recently engage in unprotected intercourse. The cramps are getting worse and worse, and the bleeding has not stopped.
