Alright - I'd love the thoughts from some of you with a bit more experience with OPKs than me.
This is my first month using OPKs. I decided to double up and use both Wondfos and ClearBlue digital tests (just to try to make sure I was reading the Wondfos correctly).
Here are my Wondfo OPKs from Friday to Sunday and the times I took them. I've also indicated what my ClearBlue Digital OPK indicated.
It looks to me like my Wondfo was close to positive (maybe actually positive) at both Friday times, definitely positive Saturday morning, and negative again by Sunday morning. But why would my ClearBlue test not be positive until after the Wondfo has returned to negative? Thoughts?
We definitely treated this weekend like prime time and I got (what appears to be) my temp spike this morning (Tuesday) so hopefully this will be my month! But if not, I'd like to understand these OPKs a little better for next time.

I experienced this too when I was using cheapies and the CBE Advanced together. I think the CBE just has a higher threshold for reading positive. I was also charting BBT, and generally found that my wondfos or babis looked positive the day before ovulation, my CBEs were positive on o-day.

I usually get 2-3 days of postives on wondfo. I use the cb fert monitor and get two peak day readings.

@lilyofthewest: This is good to hear, because I am certain I got my positive on the CBE on O day as well. Which was awfully inconvenient since I got my IUI the day AFTER I got my positive test. I think I'll purchase the Wondfos for next month.

@lilyofthewest: Well that seems to be in line with my chart for this cycle. FF is saying I ovulated on day 13 (I'd have figured day 14 personally). And day 13 is the day I got a positive on the ClearBlue (and the day after my Wondfo positive).
