Do you use Ovulation Test Sticks more than once a day?

I have just started using them yesterday. Should you just use at the same time once a day or twice? More closer to likely time of O? :confused:

I think once a day is fine, as long as you don't have to pinpoint the exact moment of O and are happy to BD for a few days in a row. I know the instructions say to wait for the line to be as strong as the control line, but I never do. As soon as I see the faint line, I know I'm catching the LH surge on the way up, so we BD for the next few days.

I have heard that some women have a very short surge though. In this case, you may need to do more than one test a day. But as long as you test every 24 hours, you should get enough warning that your surge is coming.
