Help! Yellow CM a Sign? (Not tmi)

Hi ladies! When I just went to the bathroom, I noticed I had creamy, yellowish cm. I feel like I have never noticed this before. AF was due the 21st, tested on the 20th and got a BFN. I have been experiencing headaches, constipation, fatigue, and my wine tasted off tonight. 
Has anyone had yellow CM before getting a BFP? I am 100% sure it is not an infection as it does not have an odor and I have no discomfort. 
Thanks so much in advance ladies! Baby dust to all! ✨✨✨✨
