Hi, I'm am 10 dpo today and was due af this morning but no sign. I always have a short luteral phase. 2 days ago I had a lot of cramps and thought it was af on the way but it obviously wasn't. Could it have been implantation? Is it ok to test tomorrow or is it best to wait another day or 2. Been ttc for nearly a year now and am so hoping for a bfp
