Tink13star

So been on depo for last 6 years. Last shot was Oct '18. I started bleeding the beginning of the month, very light, brownish - darker red (almost maroon). Lasted 5 days, then yesterday I started bleeding lightly again. Much lighter then the last, but same coloration. Put a liner on, just spotting, not much on pad, mostly just when I wipe. Anyone else experienced this? Just hormones, ovulation, or what?
