a gross cm and bbt question

I never do this for some reason I always thought it was kinda gross but af is set to show up tomorrow ? but I just went to the potty and found a white creamy milking watery looking cm. it's not just a little bit either it was so much it felt like I had just started. Is this a sign I've had a few questionable postives and aome clearly negative negs soo I'm unsure on the test front took on this morning and it looked neg to me but I don't have the best eyesight. Can some on shine some light on this cm and if I am possibly prego never had this cm before along with my temp I'll play my chart below. Any advice words of wisdom or just coment are welcome?
