I was just reading on line about how long you should continue to see the lh surge line on a opk strip. this one person asked if the line goes away after 48 hrs of the surge detection and someone wrote in response that if the line stays (darker or the same color) for 7 days then that is a good sign you are pg. I'm thinking this is BS but I sort of want to keep poas for the next few days to see if the lh is detcted longer. Does anyone have any thoughts on this. I freakin hate the 2ww!

Yep, I see the line for three days. If I was less obsessive about all this I'd probably stop testing, but I don't always ovulate right after my surge (as suggested by how long until AF shows.) I have never actually picked up a second surge on an OPK, though; not sure if my body just takes a long time to ovulate (i.e. no second surge) or if the second surge is smaller and non-detectable.

She has a lot of interesting info on "Using an opk as an Hpt." She does a lot of pretty interesting little "experiments" as well.
