I've been getting depo for about 9 monthes now. My last shot I had to reschedule my appointment 3 weeks later after I was suppose to get the shot. I had unprotected sec within those 3 weeks. It's been a month since I got the shot and I'm 3 weeks late on my period, do you think there's a chance that I'm pregnant? Or just missing a period because the shot?

Most likley your just missing your period bc/ of the shot. Everyone is different on and off the shot. I also just got off mine after a year , I had a light period for 3 days and then it stopped. It just takes time for the depo to get out of your system. Your body will go back to normal just give it time. Even after your off the shot it can take up to 10-12 months before the depo is out of your body. Just in case though if your not looking to get pregnant id advise you use protection. If u are not planning to have kids at any time always use protection every time. You should also use protection to protect yourself from any STDS.
