Symptoms after he depo

Can someone please tell me if the depo caused them to have complications for a while.

only had 2 injections came off it in July 2017... periods returned January 2018.

We’re irregular but since June had bleeding on and off every other week and heavy. Then had a miscarriage August.

Is this normal for the bleeding after depo?

Please I’m so nervous and overthinking everything all the time and thinking the worst 😢😢
