Depo injection period?!

I have been off the depo injection now for about 5/6 months I think. My period came back in January irregular, I had a period was off for 2 weeks came back on, then was off for 3 weeks came back on for the normal 5 days.

In Feb I started my period last week for 5 days, then had 2 days where there was nothing and now I’m going through phases over the past week of either loads of brown discharge which is dried blood which is either clotty or really runny, sometimes it can be blood, sometimes I can have nothing and then the next day back to brown?

Has anyone else had or having this problem?
