Oh, I take my temp orally! It usually rises a whole degree after ovulation and stays that way until AF.

If you know the day you ovulated, then wait about 12 days or so before you test. Some women don't get a + until 10 and others not until 14 or 16.

If you're not sure when you ovulated, then I'd just test when you'd expect AF (based on your last cycle or two). If it's neg, just wait a few more days and test again.
