Everything you need to know about ovulation tests

No matter if you are new to Natural Cycles or have been using it for a while – here are the most important things you need to know about ovulation (LH) tests.

WHY should you test for LH?

Ovulation (LH) tests are optional but can help the algorithm to detect ovulation so you can get the very most out of your Natural Cycles experience, and who doesn’t want that right?

LH stands for Luteinizing Hormone, which has its peak roughly 48hrs before ovulation and can be found in your urine. That’s why a positive LH test is a strong indication that ovulation will occur soon, but do keep in mind that it does not mean that ovulation is occurring at this moment nor that it definitely will – the body is simply getting ready to ovulate. That’s why ovulation will only be confirmed in the app after a rise in temperature has accompanied a positive LH test.

HOW do you test for LH?

You can test your urine for LH with the Natural Cycles ovulation (LH) test strips. An increase in LH is usually found within 24-48h before ovulation. LH is always present in the body, put peaks just before ovulation. So a light LH indication can be found on many days in the cycle, that’s why the test is only positive if both lines are equally strong.  You can buy the LH test strips in our Webshop and find a more detailed description of how to do a test in our FAQs.

WHEN is the best time to test for LH?

On around 3-5 days of your cycle, the Natural Cycles app will prompt you to take an LH test. This is to minimise the number of tests you need to take, without missing your LH peak. You should measure between 10am-8pm as the LH-levels tend to rise during the day. You should also try to make sure you that you haven’t visited the bathroom or taken in a lot of fluids for 2 hours prior to testing. You can take ovulation tests as many times a day as you wish to.

LH – Luteinizing hormone

 

The hormones in our body changes during the menstrual cycle, generating different reactions in the body. LH stands for luteinizing hormone and it plays an important role during our menstrual cycle. We always have a certain amount of LH in our bodies, and a surge occurs 1-3 days before ovulation when the amount of LH increases. Therefore detecting the LH-surge means that the body is initiating an ovulation.

I got positive LH-tests but Natural Cycles did not confirm my ovulation?

What is important to remember is that positive LH-test does not confirm the ovulation, it only means that it is likely that your body will initiate ovulation soon. Sometimes LH is released but no ovulation happens. If ovulation doesn’t happen, then no progesterone is released and our temperature stays low. Without the increase in progesterone, there is nothing preventing ovulation to happen in the future.

Positive LH-tests must therefore be followed by a rise in temperature (due to progesterone being released) for Natural Cycles to confirm ovulation. So if you get positive LH-tests, it’s important to keep measuring your temperature to check that it does indeed rise some days later!

 


Ovulation is confirmed in the Natural Cycles app even if I only get negative LH-tests?

Natural Cycles can confirm your ovulation even if you enter negative LH-tests. This is because negative LH-tests does not mean that you will not ovulate – perhaps you have ovulation on the same day that you measured for LH! Or maybe you tested for LH after drinking a lot of fluid which made LH in your urine less concentrated.

We recommend to measure LH between 10am-8pm, and use concentrated urine (i.e. make sure you haven’t visited the bathroom or taken in a lot of fluids the 2 hours prior to testing). Read more here about measuring LH.

How does it look in the Natural Cycles app?

The Natural Cycles app will indicate when it’s time to take an LH test in both today’s, weekly and monthly prognosis. (See video below.) If you just started with Natural Cycles after quitting the pill, or if you have very irregular cycles, the app might need to get to know you a bit better before indicating which days to test for LH. This is to avoid for you to have to take a lot of LH tests in one cycle. If that happens, it’s important to keep measuring your temperature! 🙂
