TTC after depo

September 25th was the first time EVER getting the depo shot or being on any kind of birth control. October 25-november 5 I would bleed a medium flow and spot on and off during those days. I was supposed to go back for my second shot in december but i never went back because Me and my S/O decided to stop depo because we both agreed we wanted to stay off birth control because we aren’t trying to prevent a child or prolong the process of conceiving . A couple days after I was supposed to go back to get my second shot I started my period December 20-25 which is my regular 5 day cycle(my period is usually off by the 4th day ) . December 25th during sex I

began to bleed as if i was having a regular heavy period ( we always have sex we didn’t do anything that wasn’t regular or wasn’t rough ) I only bled for that one day then bled heavily again december 31st i spotted pink blood for like 5 days and for

10 days i was spotting brown discharge until january 6th. it’s almost february and still NO AF . Has only one shot of depo messed mycycle up this bad ? the shot has been completely out of my system for 2 months now . When will i be able to conceive?
