When you get a positive OPK, it generally means that you will O within 12 to 36 hours.

OPKs are usually only positive for one day, that's completely normal. It means you should ovulate 12-36 hours after the positive. Usually you O the day after the positive test, so you may be Oing today. Keep an eye on your CM and you should be able to tell. Either way, start getting down and dirty with your man! ;)
