I checked twice a day.  As of my 10w1d appointment, my baby is measuring two day ahead of my calculated EDD based on the Wondfro.

@Jamjam:  Missing an LH surge means that your LH levels rise up leading to ovulation, but this surge can last just a few hours and by not taking an OPK right around the surge you can miss it. It is recommended that you take at least two OPKs as soon as you begin to notice dark ones or are close to ovulating. Good luck!

@Jamjam:  Also when you get a positive OPK you typically ovulate 2-3 days AFTER the positive.

I only test once a day and have not missed a surge.

@Jamjam:  I might have been the one to make that comment (I can’t remember).  Like 

@candy11 said, sometimes the surge can last just a few hours.  For some women, this isn’t an issue, but I think it was for me.  However, I had actually stopped testing for a few days (because I thought I had already ovulated – FF gave me crosshairs, but it was wrong).  I tested in the morning the day before I ended up ovulating, and the test was almost positive, but not quite.  Later in the day, it was even fainter, so I’m pretty sure that had I tested the night before I would have gotten a positive then.  I likely would have missed my surge, though, had I only been testing once a day.

@SadieBee:  +1 This. I’ve also missed my surge before. The first month for sure, because I wasn’t checking enough.
