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?
You can test anytime after about 8 dpo, but you might get a false result. Most tests are only 99% (or whatever they claim) reliable once AF is due/late. You could always get some cheapies if you can't wait that long, but be prepared that it might show negative even if you are pregnant. Not much help am I - sorry! Good luck x
If you are between 9 and 11dpo you could prob test now and it would show up if you are but there would still be a chance of a false neg so you would have to test again in a few days to make sure
The earliest you can test is 7dpo but reliably its best between 12-14dpo. If you still see no AF past 16dpo its a very good chance you are pregnant or you didnt ovulate Goodluck!
