Go to the form (swipe to the left).

Then change the date to the earliest date of your cycles. Enter the information you’d like. After you are finished filling out the form for this day, don’t confirm with the ok tick mark on the right, as you usually would, but click on the arrow that points to the right (on the left hand side). Then continue with the entry for the following day (its date will automatically show and you only have to adjust the temperature and cervix quality assessment).

After you are done entering all dates you want to enter, save your last entry by clicking on the ok tick mark on the right hand side.
