This photo is TMI...but serious

I need a few opinions. AF is due for me in about 4-5 days and I took a test this morning which turned up -- but I still feel pregnant. My nipples have become more bumpy which is weird. And I have had a yellowish snot like discharge about 2 or 3 times the past week and there's no infection. Has anyone ever had this and turned up pregnant? I had it about a week ago and it had a slight tinge of pink blood. Hoping this is it. Opinions please! And sorry for the pic again.
