Yep 12-48hrs....I've noticed that I get a positive opk for 2 days and I ovulate the day I get a negative (48hrs after I get the first positive opk)
But thats just me...some women have a shorter surge...like 12hrs so you could ovulate tomorrow maybe...so basically 2 dark lines means get to baby dancin!

I sometimes have two days of positive OPK and then within 1-2 days of that, I ovulate (temps confirm). Once I get a positive OPK I usually continue to test once a day until it goes negative again, so I have an idea of when my surge ended.
