Depo story?

Cy
Was hoping someone could help me with my story!! So I came off depo in February. So going on 7 months without it I immediately got my periods back! March and April mid cycle bleeding and then may a super normal cycle like ovulated normally no mid cycle bleeding nothing! Then June back to mid cycle bleeding when I ovulated then period around the end of the month! Then July a complete turn around brown spotting this entire month and No period also bleeding some red to but more brown when I wipe it's wierd and I don't get how I could have periods and then not idk me and my husband have been trying to conceive this entire 7 months and no luck...
