What Causes Migraine With Aura While On Marvelon?

I think I ve started having migraine with aura on marvelon. Would I continue to have aura migraines if I switch to another type of combined pill? Other then this issue I absolutely LOVE the pill so im hesitant to go off it. I ve lost a lot of weight, it s helped my depression, decreases by panic attacks from 1-3 a day to 1 a week as well as stopped my endrometriosis cramps. I ve heard of the mini pill but only negative things-weight gain, surprise pregnancies and mood issues. Would the mini pill have the same positive effects as the combination? Could my vision disturbances not be caused by migraines? Could I stay on marvelon despite the auras?
