Spotting and red discharge but no period

I am a 20 years old female. I have PCOS. 6 months ago I stopped taking Krimson and started taking supplements like Inositol, d-chiro Inositol, vitamin d, folates, etc. and followed a dairy-free, gluten-free, sugar-free diet with Flaxseeds and pumpkin seeds and green tea to get back my natural periods. In the initial months, I had predictable healthy menstrual cycles of 32 days. Only in August I noticed that  vaginal discharge was constantly stringy, slippery (ewcm) and there was no drying up so I thought it might have been an anovulatory cycle. The next two months followed well and my discharge indicated that I was ovulating (32 day cycles, the discharge until 15th day used to be watery, slippery, stringy and then would get thicker, decrease in quantity and whiter). This month the discharge was unpredictable and instead of periods, I have only been spotting and getting bloody discharge for 7 days. Why is there no flow? I'd appreciate an explanation of my problem.
