Got demoted even though i won games?

Edit: this was solveD IM JSUT DUMB

So i just got out of ranked game and i've had a winning streak ever since i was put in bronze two, i was one win away from being put up for promotion and i won a game but then i went to my profile to see i've been demoted to bronze one and I'm just very confused??? I'm almost certain i had enough lp to stay in bronze two so someone help me out or explain why i was demoted. I still have my winning streak which is why its so confusing? Idk maybe I'm just dumb and am overlooking something??
