HELP!!!

My period was due on 12/24. I have been very regular with a 27 day cycle. I have tested 6 times. All BFN. 4 were FRER before AF was due, 2 were healthy accents (food lion brand) blue die test. I am BF my son and I don't notice sensitivity in my breasts, but I have been leaking milk which I never do and I have had pimples which I only ever have when I'm about to start my period and a few toward the end of my last pregnancy. My has been high, soft/med, and closed for almost 2 weeks. Wtf?!
