I’m worrying I’m not ovulating

I’ve been with my partner for 2 months I know not long and we are not trying for a baby but we don’t use condoms and I’m not on no birth control, I was on the depo for 3 years but been of for 13 months now,before my partner now I was with someone for a year same again didn’t use condoms ect and not once did I get pregnant we wasn’t trying but I’m worrying I’m not ovulating🤷‍♀️, I was fertile before the depo, I’ve been having periods for 7 months now I’m currently on my period, my periods can be between 28-30 day cycle and I’m normally on for 6-7 days, I’m just panicking because I’ve heard horror stories about the depo 😔
