Hi, I ve been on the depo shot for birth control now & recently am gonna get my 4 shot. But, after I got the shot maybe a month after it started to hurt really bad everytime I had sex with my boyfriend. This has never happened to me.. It only hurts on the inside as if it s so sore or raw, we could go maybe a few days without having sex & it still hurts.. I don t know what the problem is ?!
