Start by entering the first day of your last menstrual bleeding. As long as you have not entered any menstruation day, Lady Cycle cannot show you the temperature curve, the calender and the analysis.

Lady Cycle Main Page

From here you can get everywhere. If you click on MENU (depending on the android phone the button below the screen) you can select Options and configure Lady Cycle to your personal usage.

On the Lady Cycle Main Page you always see your state of fertility. For the first cycle your state of fertility stays on red (fertile) during the days of your menstrual bleeding. This is because Lady Cycle does not know whether a temperature jump had occurred in your previous cycle. This is a necessary prerequisite to savely determine that your menses are infertile days!

However, from the first cycle on when a temperature jump was determined, Lady Cycle uses the standard rules of the symptothermal method to determine your state of fertility.



Entry Form

The entry form is divided into Basic and Advanced.

In the Basic Form you can enter all data that is necessary to determine your state of fertility. In the Advanced Form you can make additional entries regarding your psychological and physiological well-being and enter symptoms.

Just complete the form, leave everything empty that you do not want to fill out (yet) and click on the tick mark on the bottom of the form to save your entry. The entry for a given day can be adjusted at any time. This way you can easily adjust for example your highest perceived cervical mucus quality when you note in the afternoon or evening that it has changed.

Besides saving your entry, you can also use the other buttons to quickly enter a number of days that follow each other (for example, if you would like to enter previous cycles), if you would like to delete an entry or if you would like to discard your changes to the entry of a given date.




The display shows you your temperature curve. The infertile periods of the cycle are indicated by the green background, the fertile period by the violet background. You can also see the strength of your menstrual bleeding (at the beginning of the cycle), your cervical mucus quality and cervix position, firmness and opening (in case you entered it).




In the calender you are given an overview by month and you can jump directly to the date you would like to enter in the entry form. Please be aware that the date you meant to click on is the one that correspondingly shows in the entry form. You can of course also use the entry form directly to adjust the date (by just clicking below Date, see above).

Manual Analysis

Begin fertile period

If you would like to use the 8-day rule that affects the begin of your fertile period at the start of each cycle from the beginning of using Lady Cycle because you already have 12 previous valid cycles from where you know the earliest day of temperature increase across cycle, you can do this.

Just click on MENU, preferences and adjust the first day of increased temperature across the (at least) last 12 cycles.

In the preferences you can also do many other specifications such as entering your average cycle duration, minimal cycle duration etc.

You can also chose, adjust or delete your personal password in the preferences.




End fertile period

Click on the MENU button of your Android phone when you are looking at the DISPLAY. Here you can adjust the end day of the fertile period manually if needed.

Note that you can always exclude certain data entries from being taken into the automatic fertility calculation by adding a temperature disturbance to the entry at the specific date in the form.
