Depo Shot


The other day I got my Depo shot, I use it more for my cramps because they used to get really bad, I'm not currently sexually active(recent big breakup). Anyways, when the doctor went to give me the injection, a lot(majority) spilt on my arm and pants. I wasnt looking (I hate needles) so I couldnt tell if it came back out my arm or out of the needle. He didnt seem to be rushing and he seemed very surprised because he said there was "resistance" and that he hasnt had that happen. I usually go to my community health center for the injection but it had closed and I was already late on getting it done. Was the vial bad? was I too tense? did the doctor mess up? Idk. Any advice?
