confused

Laura • TTCING baby #3 since November 2011
I am on cycle day 40, I am 5 days late. I have had two BFN but tonight I had ALOT of egg white mucus with a few small specs of blood, then some pinkish discharge after sex. My calendar puts me being fertile between the 18-24th I also had a little spotting on the 8th. I literally have no clue what is going on right now!!
