CD 17, what is happening!?'

So I am in cd17, the last few months have been ovulating, with cycles 26-29 days apart. 
This month it's ALL wacky! Started soy 2-6, for the second month. 
Also added pre seed and softcups. 
Starting cd8, testing opk. Vvfl in cd9 and absolutely no color outside of the control despite testing twice a day. This is off, prior months I always have some sort of line to work with.
My temp dipped then rose indication of "O" CD12, so I thought. 
Temp has been erratic since. Dipped way low again cd15 then rose higher than all month. Today temp is 98.08
Glow predicted fertility days, bd daily with the pre seed and softcups. I started seeing some blood specs in soft cup cd13. Yesterday it was more brown and enough to mark the liner during the day. 
This morning, I saw a larger amt of bleeding, and not sure what the deal is!'AF is NOT due for another 2 weeks!!
Had this happened to anyone where it resulted in a bfp
I am also taking pre natal, coq10, melatonin and added b complex, and small any of zinc since I thought that I ovulated.
Bfn this morning btw, and negative opk last night.
Is it af, and just move on or something else. I am 43.
