Let me get this straight...
You can O but never get a +OPK because it's easy to miss your surge.
Conversely, you can get a + but not actually ovulate (body gears up to but doesn't kick the egg out).
In other words, you can never really trust the result. Am I missing something here or does anyone else find this completely useless? Thinking I will not be buying more OPKs once I run out.
Re: Is it just me or are OPKs pretty much worthless?
I keep hearing about this on this board, but I'd be interested to know how often this really happens. What are the reasons your body would gear up to ovulate and then not actually ovulate?

I don't find them to be completely useless. I use OPKs and temp and they always match up. It's not the OPKs fault that it detects you gearing up and your body changes it's mind.
They would be completely useless for ttc if they confirmed you ovulated after the fact or the day of since you should have sex right before you O.

Thanks! I love that site very useful.

I trust the result of OPK's, I don't temp. I know my body and the ovulation signs very well. Plus, I think as long as you keep up doing the deed at least 2 times a week at all times, you're pretty much still going to hit your fertile window, even if it happens later than you think.

Yes - you can gear up to O and not ovulate due to a stressuful event. Illness can also cause this to happen.
The best time to BD is when you're about to ovulate. If you rely on CM, you may BD too soon (the sperm may survive up to 5 days, but they also may not). If you wait for the temp spike, the egg will have already come and gone. By using an OPK you get a 12-36 hours window of warning that the egg is coming, and thus can engage in some very well-timed BD.

For me, they work fine. If I get a positive OPK, it's my sign to have a little extra sex. Once my temps increase, it validates the positive OPKs.
I've been using OPKs for the past two cycles and have yet to get a +, but I wouldn't call them worthless. I'm going to keep trying to catch my surge, upping my testing times to 3x a day this coming cycle, but even if they never work for me I recognize they work for others. Plus, I love peeing on tests.

I ran across this article about the best and worst HPTs and OPKs.
https://www.cbsnews.com/stories/2003/01/27/earlyshow/health/main538075.shtml
Interestingly, the article states that the OPKs they tested are not that great in detecting the LH surge in many women. Now, this was eight years ago so who knows how that's changed. I used OPKs for the first time last month and got a positive on CD 16 and the morning of CD 17 with the Wondfos I bought on Amazon. I also tested with the Answer ovulation tests I bought at Wal-Mart and never got a positive. FF confirmed O on CD 17 based on my temperatures. I'm sticking with the Wondfos this month.

You may just have a short window, making it tough for you to catch. But still, if you can see them getting darker, they are still telling you it's coming.... therefore NOT totally useless.
