Stopped depo 7 months ago now what??

So I had two depo shots and my last one was 7 months ago.. I had my first real period in March and every month since I’ve had somewhat normal periods I was wondering if my periods would ever return to normal.. I had my period every month on time before depo.. I’m now scared I can’t have children. Please comment your thoughts. This month I had some really thick clumpy discharge that was literally just falling out of me. I don’t think I’m pregnant and I have no stds
