Frequently Asked Questions
Yes, our fertility trackers can be used while breastfeeding. You should not start measuring until 6 weeks after birth. Since there is no way to predict the first ovulation after birth, Lady-Comp/Pearly will show yellow (learning phase/cycle fluctuation) until the first menstruation is entered postpartum. Once you enter your first period, Lady-Comp/Pearly will display fewer red and yellow days in the following 2-4 cycles as Lady-Comp/Pearly gets to know your unique cycle rhythm.
No. Lady-Comp/Pearly only records the first daily measurement. If you have concerns about a reading, please contact our customer service team.
Lady-Comp: Simply press the circle button and your fertility status will be indicated by the color of the display. If you want to see details, press the circle button twice more.
Pearly: Please press any button to turn on Pearly, and then press the center button to see your temperature, fertility indicator, cycle day and menstruation entry (if applicable).
Please contact your customer service for guidance.
Use Lady-Comp/Pearly in the morning right after waking up, before getting up and becoming active. Measure below your tongue, with your mouth closed. We do recommend that you sleep 3-4 hours before measuring.
Ideally, you measure daily. The fewer measurements you miss, the better.
When staying in other time zones, set your cycle computer to the local time immediately after arrival and activate the alarm. If the time lag is more than 6 hours, we recommend skipping the measurement on the same day and the following day. Instead, you continue to measure as usual on the day after.
Before you start using a cycle computer, you must stop taking the pill. It influences your body’s hormone production. As soon as you have stopped taking the pill, you may start measuring your temperature with your cycle computer. Please be aware that the first bleeding after coming off hormonal birth control is a withdrawal bleeding and must not be entered as your period. If you are menstruating when starting with your fertility tracker and you cannot enter all days, do not enter the current menstruation, but the next one. The first day of menstruation is important because it marks the beginning of your cycle.
Only very few (hormone-free) medications have a direct influence on your measurements, but often the reason why you are taking medication can influence your temperature (e.g. fever or stress). Hormonal medication will influence your temperature and should under no circumstances be taken in combination with Daysy. If you're unsure, consult with your doctor or contact our customer service.
Based on their recorded data, our fertility tracker can compensate for the occasional missed reading. We still recommend you measure as regularly as possible so that your fertile phase can be narrowed down as precisely as possible. If you have to skip measurements due to illness, Lady-Comp/Pearly will get back on track once you start again.
You can rely on Lady-Comp´s/Pearly´s results starting the very first day of use. In the beginning, you will see more yellow and red days because Lady-Comp/Pearly is still learning your unique cycle. You will see more green days as the device comes to understand your cycle and can narrow down your fertile window. The more regularly you measure, the better.
Smoking should not influence the result. Alcohol, if consumed excessively or when your body is not used to it, does influence basal body temperature. If you can feel that you were drinking yesterday, you should skip your reading in the morning. If you feel just fine and have no headache or other symptoms of alcohol consumption, you are fine to temp as usual.
The non-hormonal IUD prevents the implantation of a fertilized egg in the mucous membrane of the uterus. Because the IUD is a foreign object inside the body, it causes the production of white blood cells - similar to inflammation. These small centres of inflammation in the uterus, which are normally not detected at all, can change the waking temperature. In order to obtain precise measurement results, it is therefore advisable to remove the spiral - and only then use a cycle computer.
If your efforts to become pregnant have not been successful within six to twelve months, consult your physician.
Yes. Our fertility trackers have been developed to accurately recognize cycles that range between 19 and 56 days. However, using Lady-Comp or Pearly with extreme fluctuations would lead to a higher number of red/yellow days. Fluctuations of up to several days are no problem. If you have questions about your unique cycle, please reach out to our team of experts.
Lady-Comp runs with 2 AAA batteries and Pearly with 1 AAA battery. You can also use rechargeable AAA batteries.
