TMI discharge!

I’ve been getting white discharge like the tissue paper but it’s spongy, not like cottage cheese. Before my period for the past 2 months. Once I get my period it stops. Is it normal? I also have Endo, and PCOS, and I’m on the pill. It doesn’t itch or burn or have a weird smell. It’s normal except for the texture. I’m waiting to be been by a doctor, and I’m thinking of just getting OTC medication for a yeast infection but I’m not sure if that is what It is.
