Don`t Take Depro

I started to take my first shot and a couple of weeks after I got the shot I got my period for a month and a week. I called my doctor and he said that it is normal and that it will regulate when you get the 2nd shot. I went and took the second shot and a week later I got my period for another month. I thought that would be the end of it but 2 weeks later I got my period again til this date and it has already been a month and a half and I am bleeding fluently which scares me but all they say it is that it regulates the next shot. If you think abou it throughout my 2nd shot I`ve had my period for two months and a half and more coming. That is all a lie. I have had the worst experience with this shot and I will never took the 3rd shot or ever will. I did the shot so I can enjoy my sex life while being protected. Ofcourse you`ll never get pregnant cuz you never have sex.
