Realistically. I don't want to test early. AF is due between 21st-23rd. I think I ov'd (according to the net anyway) between the 3rd and the 5th of this month, so 9-11dpo. My cycles are long 30-31 days. On CD24 I think but can't be sure. Do I wait untill AF is late or is there a certain dpo you can test past?
