Depo Provera but getting really unpromising spell pains...?

My next Depo shot is due on 17th of this month but I'm immediately getting really bad time of year pains.
This happened later time and they gave me a shot hasty. What do you reckon is going on? Depo is EVIL thats what is going on... everyone I know who has be on depo (including myself) was so messed up from it! After I stopped getting the shots I did not hold a period for 18 months.. during that time I have two pregnancy tests that be positive, yet I be not pregnant.. then I DID attain pregnant, but the test come back gloomy! I am just grateful that my little boy be not born with serious issues.. Depo = evil
adjectives contaceptives are not suitable for everyone,it could be your body rejecting it.I would try something else
