Hi everyone, I'm a new member 😀. On Monday last week I went to get the depo provera injection. I had unprotected sex probably a week or two before this (he didn't finish in me) and I was due to start my period on the Wednesday after receiving the injection. The nursed did tell me my period would probably be delayed and I still haven't had it (two days after the due date). I'm just a bit confused as to whether it is the injection because she told me I wouldn't be protected from it until after seven days so I assumed that it wouldn't have started working until then. Has it started working but not enough to protect me yet?
