Positive OPT for two days. When is O?

[Niva]

Today is the second day in a row I've gotten a positive ovulation test strip. Will I likely O the day after the last positive, or the day after the first positive? I think it's the last, but wanted to see if anyone knew for sure. Thanks!

Also, do we generally O at a certain time of day? Or can it be any time?

You will usually O 12 - 36 hours after first +OPK. Your surge comes before you O. You can O at any time of the day.
