Help πŸ˜”πŸ˜©

So I've come off birth control after having a medical termination due to serious birth defects that weren't survivable. I just needed a few months to get myself back on track so I had the injection. Only the one. My last one was beginning of may when the procedure was done, I've had one period since which was Aug (end) but have had bleeding on and off for last few days. Could any tell me if I'm back to normal and ovulating? Thanks πŸ˜”
