What is going on?

Ronda • TTC #1 since Sept 2013.
So I have something strange happening. AF was six days late and I thought she came yesterday when I saw some blood when I wiped. But since then there's been nothing. No bleeding, never any clots. My breasts are sore and I haven't been feeling well at all. I tested several times before yesterday and always had a BFN
Any insight here ladies?
