I have been on the depo shot for about 9 months now but i’ve recently missed my last shot. They told me to wait until the first day of my next period to start it again. Two days ago i was spotting and had really bad cramps so i assumed that it was period and i scheduled an appointment for my shot tomorrow but during those two days i haven’t bled . Will i be okay to get my depo shot & could i have a chance of getting pregnant if i do this wrong ?
