TMI Help me

So 3 weeks ago today I started birth control pills. Well last week I thought I had a yeast infection cause I have tacky cottage cheese looking discharge. I’ve also been burning for a good 2 weeks now when I pee. And I’ve taken uti medicine and all. Well today I experience so much discharge looking like this. Can this be from the yeast infection or can it be the starting of another infection or is it just the birth control. Also I’m ovulating right now
