Could it be implantation or af?

Sorry about the long post.

I tested with fmu on Tuesday BFN with a cheap hpt from Amazon. I then decided if my temp was still up Wednesday I'd test with a fr, however when I did my cervix check before I dipped the test I had some pink blood on my finger I had just assumed af was coming so I didnt test and nothing all day when I wiped. All day today I had what's in the picture or brown on the pantie liner.

I decided just before my fertile week to start temping and didnt get my thermometer untill after I had started my fertile week.

What do you think af or implantation?
