I've had something similar happen to me before, and its really down to the individual - have the stressors eased? Has it stayed the same? Has anything got worse?

Mine was the opposite - I had AF for about 8-9weeks non-stop, but it was also a result of stress. I think you should expect AF once life has settled down.

The depo shot might change it I guess, but I don't know if theres any way to tell
