Yes, a few days before I tested positive I thought for sure AF was coming. I only tested just to make sure it was okay to stop the progesterone. To my surprise it was an instant BFP. I am know a little over a 11wks and I still get crazy twinges and pressure every know and then. I think we spend to much time over analyzing or body and it just drives us mad!!!!!!
Good luck, I hope you get the outcome you want!
