Birth control

I’m on the depo shot. Got it on the 2. The problem I’m having is that I’m constantly bleeding, every day. Last time it was just spotting, coming on n off, or come then stop then come back. But on the 22 it started coming fully and I’m still bleeding. I don’t know what to do. I also been having stomach aches and huge cravings.

I don’t know if i should continue being on this and if it’s normal and I’m okay or switch to the pills

My first time being on birth control
