I received the Depo shot for the first time ever while I was NOT on my cycle. I got the shot on July 6th. My last period started June 28th and ended July 3rd (3 days before I got the shot). I had unprotected sex with my bf and he finished inside me on July 10th. I read that if you get the shot off your cycle you should wait 7 days for it to be effective, but I only waited 5 days. Should I be worried? (I was on the birth control pill for 2 years prior). Please let me know if I should get Plan B or if I am covered
