How myLotus works

If you’ve got an irregular or longer than ‘average’ cycle, the chances are other ovulation tests won’t work for you. That’s where our fertility monitor comes in.

The myLotus Fertility Monitor can cover the length of cycles that range from 21 - 42 days. It learns from previous cycles and it can pinpoint your exact LH levels, even if your periods are on pause.

Simply test your urine each morning and we’ll tell you the precise amount of Luteinising Hormone in your system. By tracking your LH each day, you’ll get an overview of your own LH curve so you know when you’re most fertile.

Start tracking and you’ll get real-time, lab-standard test results, letting you know exactly what’s going on in your body. 

Why LH?

Ovulation usually happens between days 11 and 21 of your menstrual cycle. A hormone called luteinizing hormone (LH for short) surges, triggering the release of an egg. 

It’s important to remember we’re all different. A recent study* shows 88% of women have their fertile days outside of the ‘standard’ clinical windows - that means before cycle day 10 and after cycle day 17.

don’t do average

We’ve spent years developing proprietary technology so that you can precisely measure and quantify your LH levels. This means that when natural conception is your primary aim, be it timed intercourse,  or further supported using intrauterine insemination (IUI), or frozen embryo transfer, specific timing is fundamental to success.

Guessing won’t get you pregnant. Tracking might.

Every month matters and every body is different - that’s why tracking your LH allows you to understand your cycle.

Your LH surge happens around 24-36 hours before you ovulate. The day that your LH surge is detected, and the day after, are the two most fertile days in your cycle. Knowing the exact timing can improve your chances of pregnancy.

Research shows that testing mid-morning gives you the most accurate result, but the LH surge can happen at different times for each woman. When it does happen, it can be very rapid, so testing twice per day can help you spot your peak before your LH levels start to come down.

When you see that surge coming. Get busy.

The day you see a surge in LH means there’s an egg ready and waiting to be fertilised. You should then have sex within 24 - 36 hours.


I love how easy it is to use, but the best thing about it is that it gives you your own personal levels which you can track on the app. Definitely worth the money.


Absolutely amazing little machine & app, that have allowed me to see when I am ovulating as well as accurately predicting my cycle, even with having an irregular cycle & having PCOS. I would highly recommend this product to anyone trying to conceive or to just better understand their body.


Really easy to use and helpful for if you're unsure about ovulation. Perfect for if you are unsure about your own cycle or have irregular cycles


This is a great, less intrusive, device for those ladies who are struggling with irregular cycles. MyLotus customer service is always great and the team are very supportive.


This is the best monitor by far I have used to track my fertility. It even works for women like me who have longer and slightly irregular cycles. It gives your your personal LH level so it completely takes away the guesswork you have with regular OPKs.
