If you are not pregnant and don’t have periods or have them with great irregularity, you can still use the tracker to monitor your LH concentration levels. When you would like to test, press BOOKLET, and select the ‘X’ of the menstrual icon. The ‘Any Test’ symbol will appear, and you can then test your LH levels. You can plot your LH results on the graph paper provided in this pack and get a profile of your LH hormone fluctuations. This will provide you with further information that can be discussed with your doctor.
