what's your take on this?!

Helllo!!!
I'd love to hear other people's advice/experience if you all don't mind! I'm 5-6 DPO and am having brown creamy CM today (I swear it smells off but maybe I'm over analyzing) and it almost feels like pressure down there. A couple days ago I had a significant amout of really thick CM, more than every before. 
Has anyone had this before and if so could it be a sign of AF or maybe a good sign? 
Thanks in advance and busy dust!!
