A month long period?

I’ve had my period for almost a month now as of the 23rd, I just came off of Depo is that normal? I’ve NEVER had this happen and I’ve had it for almost two years. My back hurts so bad. I’m so tired of this, I’m currently TTC and this is putting all that on hold, my husband is an OTR truck driver, so my time is limited, (he’s home 4 days a month) any tips? Anything that can help?!
