I used a Clearblue test this am, still bfn. Not a digi, just a regular. Last time we dtd was on cd17. I on cd27 today, experienced AF style cramping all afternoon yesterday. Thought I was going to start...not sure on dpo, as I didn't use OPK this cycle. My only hope is that I ovulated late this cycle, and could possibly be experiencing implementation right around now. I'm out of tests, so now it's just a waiting game.
