menstrual cycle calculator
Simply calculate your monthly cycle with Daysy
In order for Daysy to be able to show you every day whether you are currently fertile, simply use it to take your morning basal temperature by activating it and placing its sensitive test prod underneath your tongue. Stay in bed while you wait for 30 to 60 seconds for the measurement to finish. Daysy might then ask you to confirm that you currently have your period. That too is done via the simple and quick push of a button. Already Daysy has all she needs to calculate your fertility.
Right away, the result is displayed via a colourful light. If Daysy's green light is on, it means that you will not be fertile during the next 24 hours and also do not require to use contraception. On your green days it is highly unlikely to get pregnant. If, however, the red light is on, you are currently fertile – and if the red light is flashing, you are highly fertile and currently ovulating. During red days you can get pregnant at any time. You should therefore either avoid to have sex on those days, or use a barrier method when having sex. Condoms and diaphragms are particularly suited, because they can be used only when you require them.
Daysy's menstrual cycle calculator: accuracy through science
Daysy's accuracy has a solid scientific basis: More than three decades of research and development were necessary to make Daysy the safe device that it is. For the development of its unique algorithm, 5 million female cycles were recorded and evaluated. Beyond that, the LadyComp has successfully been using Daysy's software for many years and proven its value. When applied correctly, Daysy offers 99,4% accuracy in calculating your fertility, equaling a very good Pearl Index of 0,6!
Daysy itself is not a method of contraception - Daysy shows you when you have to use contraception. Did you know that every woman can only get pregnant during a maximum of six days of her cycle? Only on the day of ovulation as well as up to five days prior is conception even possible, because the egg can only be fertilised for up to 18 hours after ovulating. If no fertilisation takes place during this time, no pregnancy will ensue. The reason for your additional fertile days is that sperm can wait for the egg inside the fallopian tubes for several days. Once the fertile period has passed, you will not be fertile until your next fertile phase and cannot get pregnant when having sex.
Daysy lets you know when your fertile and infertile phases are happening, leaving you free to decide whether you want to have sex on your fertile days or not. If you would like to get pregnant, you can use your knowledge to increase your chances for a pregnancy by having sex at the right time. Regardless your situation, you can use the menstrual cycle calculator Daysy in a way that fits your individual life and plans.
