    @mtnhoney:  If you can, get the wondfo’s off Amazon. They are so inexpensive and a lot of bees use them. I found the best way to use opk’s is twice a day. First month I missed my o because I only did morning tests. 2nd month tested morning and night and got my positive… And got pregnant. 🙂 good luck!!

    For what it’s worth, I have never been able to get a true positive reading on OPKs. I’ve used the Wondfo ones and I’ve never gotten anywhere close to as dark as the first line. Although, I’m now discovering that I may not be consistently ovulating so that might explain the OPK issues I have.

    I have heard there are OPK brands that give you a smiley face and that takes care of a lot of the ambiguity. As far as your results this week, maybe you just have a short surge? Good luck this cycle!

    I switched to digital OPKs.  There are pricey, but I was having a lot of trouble with the other kind.  I think part of the problem was that my surge was on day 14 in one cycle and day 22 in another cycle – so I stopped testing too soon in the start.  Once I have a good idea of when my surge should be I will switch back to the other kind – maybe another 2 cycles or so.

    My doc says CM along with OPKs is the way to go since I am not charting my temps.  He also says twice a day when I think I am near the surge!

    I’m assuming OPK’s work by detecting hormone levels in the urine? If so then you might find it best to take the test on your first wee of the day when levels will be at their most concentrated (if you’re not already doing so).

    ETA: Just used my mighty friend google, that suggests that the optimum time is supposed to fall between 2pm and 2.30pm. It also suggest to try and reduce the amount of liquids you drink for about two hours before you do the test. Too much liquid will dilute your urine, which could make it more difficult to detect the surge.

    If you really are struggling with interpretation, do as PPs have mentioned and use a digital kit that will give you a clear yes or no answer.

    this is my 4th cycle charting.  So I’ve had 3 complete cycles and I’ve always gotten a clear reading on the opks I used.  2 of the 3 months I tested just once per day, one time around 10am and another time sometime in the afternoon, can’t remember.  1 of the cycles, just curious how long the peak surge lasted, i tested at 9am, 1pm, and 6pm, and they were all positive.  But I’ve never had a positive longer than a day  .  If I’m far out from o, the test will be stark white.  If I’m within a day of it, I’ll see a faint line and can pretty much know if I test in the next 12-24 hours, it will be positive.

    fyi, you usually ovulate 12-48 hours after you get a positive opk.

    I’ve been using OPKS since I started trying to conceive my daughter back in 2008 (and I’m using them now, ttc #2), I have always gotten two days of positives, some random months I get three. I test for the first time (usually, sometimes I’m just curious) around 4pm, and then again at 10pm or so. I’ve used the Wondfos forever, and I’m really happy with them! I get EWCM the two days I get pos opks.

    I usually test once a day in the afternoon starting around CD8 or 9, and when I see fertile CM (usually 2-3 days before O), I start testing more than once a day, especially if it seems like they’re getting darker. I usually get a fade-in starting a few hours to one day before my OPK is truly positive.

    Quite honestly they’ve never worked for me.
