opks--who do I believe?!

[Hobbermittens]

I got a +opk on my Wondfo tests, but the First Response test says negative (though fading in, but not nearly as dark as the control line)! Which do you think is right?? I peed in a cup and used the same urine for both tests.

I tried uploading a picture, but it won't work.

I had the same thing happen to me last time...I just went w/the Wondfos b/c that's what I usually use anyway as they're cheaper...I would say try to stick w/the ones you usually use (if there is one type) b/c using different kinds can really screw you up. Not sure if this helps you but good :luck: Hobber...

Well there is either a detectable amount of LH horemone in your urine or there isn't. If one picks it up i'd say go with that, as it would be more likely to get a false negative than a false positive.

I have used the Wondfos for a long time, but they can sometimes be a little funky, so this time I got both kinds so I could see if they agreed...apparently, they don't! :sigh:

Some OPKs are more sensitive than others so that could be why one is positive and one is negative?

:agree: Cinss - the one that is positive is more sensitive than the other - you might want to assume you'll be Oing slightly further out than you do when you get a pos. with the other test.

So I should go by the test that wasn't positive? Does that mean the Wondfo tests pick up the LH surge before it is a surge, or what? The other one (FR) turned positive this morning around 10. I will take another FR test later this afternoon and see what it says.

Okay, I was wrong... it never turned fully positive. It got close, but never as dark as the control line. I used an entire pack and even though my Wondfos faded in, turned + for more than 24 hrs, and have started fading out, the FR never changed much! I think I got a bad box.

WEIRD!~ Thanks for updating!

I once had a bad pg test - the entire box turned pink and I thought I was preggo for a month (no symptoms and I doubted it the whole time but pg tests used to be super expensive so I never took another) before I finally got AF. I think they just used too much dye on the control line.
