The better you know your menstrual cycle, the more precisely you will be able to define your fertile days. For this, measure your temperature at the same time every morning on waking. If there is a distinct increase, it is a sign that you have ovulated and that you could become pregnant. If you now continue to measure your next few cycles and track your temperature curve, you will be able to predict your next ovulation with reasonable accuracy. The perfect time to fertilise the egg is in the following hours. And, if in the next month the temperature peak lasts longer than eighteen days, then let us congratulate you: you are probably pregnant.
To calculate your fertile days easily, you can of course also use a fertility calendar.
* Important! A fertility calendar is based on a simple calculation of averages. We strongly advise you against using this as a method of contraception. Should your cycle be very short or unusually long, you should speak to your gynaecologist in order to exclude any possible disorders.
