help what the heck is this?! warning TMI

hi ladies, really need some help! I was 7dpo yesterday and took FRER and cheapie Boots drugstore strip test - both got vfp. today I'm 8dpo and three tests (FRER and one clear blue) said bfn. then I go to the loo to check my CM and I get the below! it's much thicker than ewcm and super stretchy but I have no clue what CM this is! over the past 8 days I've had high temperature (between 36.7 and 37) on my daily charting and then a dip today (36.4) please help me identify this. Is this a good sign or early sign of pregnancy?
