can anyone give me an idea what this is?

hello ladies. i am suppose to start AF in 2 days. I am very in tune with my body and know right before AF I either have watery cm or dry. I have noticed loads of creamy CM, and EWCM. I know I am not late ovulating, opk had no LH surge and i do not have any infection, no iching or burning. does anybody know why I would be having this? Yes I am TTC. Any ideas would help! I had some very light pink spotting about 3 days ago, about 3/4 times within a two day span. nothing heavy, just spotting every now and then when i would wipe.
