abnormal uterine bleeding
"Got the shot in December 2015 was fine until I was due for my period in January. 
Spotting started and after sex it would get worst. 
It kept going through the whole period and ovulation, till about a week ago when it stopped. 
Today I'm due for my next period. Don't know if it'll started again or if I'm good or not. 
I will not be continuing with the shot. I'm hoping I can find a good birth control pill instead."
