Any one waiting for the BFP and when my due date for AF is Oct 14?

Hey! I'm also TTC and my AF is due October 15th. I've been having killer headaches and a little bit of nausea when I wake up each morning. In addition, I've been having light cramping the past few days and I had light spotting on Sept. 27th. I'm praying AF doesn't come!! I had a chemical pregnancy back in August. Good luck!!!
