How to know thru opk when we are most fertile?

Question

I check opk for my most fertile 8 days , between that only one day (23rd day of my cycle ) it shows very little color change.
On the catalogue of opk says it will gradually change the color into more dark red shade , for my case only one day i seen very little colour change ,

Answer 1

The short answer is that you really *can't* know by using an ovulation predictor kit when you are most fertile. It is only a best guess. An OPK determines when your body is *preparing* for ovulation, not when it actually *will* happen. There is a serious but subtle difference between the two. Your body can prepare for ovulation, then "change its mind" and not ovulate. In this case, you may ovulate several days--or even weeks--later. Or not at all.

If you aren't getting an accurate reading at all, you could call the manufacturer and ask them. But I would suggest you don't bother with the OPK at all.

Instead, read _Taking Charge of Your Fertility_ by Toni Weschler. It will tell you how to determine more accurately when you will be fertile and ovulating.

What does an OPK tell me? The female body produces something called luteinizing hormone (LH.) It is present in the urine almost all the time, but increases significantly-- surges-- about 12-36 hours before ovulation. An OPK detects LH in your urine and gives you a positive result when it detects this surge. (If you read this page before and saw "aluminizing hormone," no, you're not crazy. That's what happens when you trust spellcheck and let it "correct" words for you. Hahaha . . . yup, with Aluminizing Hormone, we can all turn into Pepsi cans. If you turn into Diet Pepsi, you're ovulating ;)

If you are trying to conceive, OPK's can help. They are a "crystal ball" that lets you know your egg is probably getting ripe, and the time is right for snuggling! If you are using NFP or FAM, OPK's can be used in conjunction with basal temperatures and cervical mucus to help discern periods of fertility and infertility. A positive OPK does not guarantee that you will ovulate. See this FAQ for details!

How do I read the results of an OPK? This is very important: OPK's are not read like HPT's. An OPK has a "control" line and a "test" line, just like an HPT. Unlike an HPT, however, the mere presence of a "test" line does not mean the test is positive. The test line must be as dark as, or darker than, the control line to be a positive result (meaning that a surge was detected, rather than the ordinary amount of LH usually found in your urine every day.) Note: there are now some OPK's that read more like a pregnancy test, where the presence of any second line indicates a positive result. I have not personally seen these. Be sure to read the instructions that come with your tests if there is any doubt what type you have!

Sometimes it is hard to read the results of an OPK-- the test line looks almost the same as the control line, but you're not quiiiiite sure. Some brands develop "half-positive" results where only the edge of the test line is dark (see FAQ 13; this is a positive result.) You may find it takes a "practice" cycle or two to learn what a positive looks like for YOU. You may also have clearer results with a different brand of test.

If you're charting your basal temperature and/or cervical mucus, OPK's can help you identify the approximate time of ovulation.

How do I know when to use an OPK? If you've been charting, you probably know approximately when you ovulate each month. Start using your OPK's a few days before you think you may ovulate.

If you have no idea whatsoever, take the shortest cycle you've had in the past 6 months and then use this chart to determine what day of your cycle you should begin testing:
