ttc- cd40 graphic pictures

So I am in need of some insight. I am currently on CD40, af was due on 2/3. I have had some pinkish watery cm when wiped for a couple days last week, just once a day or every other day. Saturday 2/9 I had a glob of tan-ish brown cm when wiped but nothing after that. Today when I wiped I had this... then absolutely nothing after. I tested 2/3 and got a bfn so I think I am out. I have no symptoms besides pinchy breast every now and than and tired at random times of the day. I thought I was out after my bfn but this has me curious now. Any thoughts. Anyone have this before a BFP?
