Anyone else experience spotting on Yaz?

I’ve been on it for over 3 months now and I’m still getting it. You’d think my body would be acclimated by now. I essentially have my period for 3 weeks. It sucks. I even had minor cramps the other day.
Is it because the hormone level is so low compared to other pills? Anyone else experienced this with Yaz? I’ve been on Ortho Tri Cyclen Lo and Yasmin in the past and this has never happened.
