HELP!! What is this??

I’m on the placebos of a new brand of birth control. Yesterday and the day before I had light spotting (1st picture) then today I was in the bath and this came out. Should I consider this my period??? Or what else could this be. I’ve been on birth control for over a year but this is just a new brand I’ve been put on. I’ve always had normal/heavy periods on the pill.
