Period while on Depo

Jah • 💏❤️💍🙏👶🏽

I got my first shot of Depo in December2019. My husband and I decided to conceive again. But my period has been on since Christmas! I’ve never experienced a 2 month period.

I’m wondering does this mean my Depo shot was ineffective and I have a chance at conceiving like now?

Back story: I was on DEPO for about 3 years straight and never had a period in the duration of that timeframe.
