Fertile CM on last days of depo

As soon as this depo is finished I wanna ttc. I know it takes a while after the last shot but that hasnt been the case for me I get pregnant instantly after missing my shot (wasnt ttc back then lol) so I wanna start ttc already. (My next one is due in a few days but we still have been baby dancing) is it possible I'm already ovulating ? I had fertile CM yesterday and today. Like raw egg whites for sure. Or does this normally happen even on depo.

Edit : my opk gets here tomorrow to start testing. Just wanted to know if its possible. and no usually when I'm on the shot I never get cm like this. Maybe I should keep bd lol
