I got the depo shot 3 days after my period about 1ish in the afternoon, I had unprotected sex the morning after my shot? Could I be pregnant? My dr didn't tell me how long to wait till I had unprotected sex and I did a quick google search and I read if you get the shot 5 days after your period stops you are protected then on morning 4 after I had unprotected sex I was worried and doing more research and I see so many different answers. Now I'm terrified!
