last year I found out that its red, black, brown, yellow and green. Do I have to make up my salaah since I became baaligh?

Regarding Fatwa 13974. I am following the last ruling. When I received the fatwa I back tracked my haydh dates till I could remember that is till January and then I counted as said in the fatwa. Recently a thought came into my mind that maybe I need to count back further like I remember in Ramadan that after my haydh I didn’t have a clean period of 15 days after this I don’t know what happened although I do remember having haydh (red, brown and black) once. I don’t know about yellow discharge and I don’t know if I had clean period of 15 days or not. Do I have to count back from Ramadan or further?

Also when I became baaligh I was taught that red, black and brown is haydh. Only recently that is last year I found out that its red, black, brown, yellow and green. Do I have to make up my salaah since I became baaligh? Because I do remember having yellow discharge but what times I don’t remember
