Can someone please give me some advice on ( how long do it take to ovulate after coming off birth control,

I have come off my birth control ( Arm implant ) on the start of August, I’ve had 2 period since then. period in August and also also period in September, but I never ovulated. Is this normal, I am scared the implant have ruined my ovulation. Am I been stupid thinking this or am I just better waiting to see if my body will go back to normal and I will ovulate again, also have this ever happened to anyone before not ovulating after coming off birth control,
