How to predict the ovulation?

Author: Janina Kunert

Your fertile days during each cycle are only temporary and therefore the possibility to get pregnant limited to these days. During these days, rising estrogen causes the follicle to ovulate and release an egg. The egg is only fertile for 24 hours. Male sperm can survive for about 5 days inside a woman's body depending on the conditions.

The ovulation usually occurs mid-cycle, but may vary from ovulation to ovulation due to external influences like stress, illnes or others. Therefore the ovulation predictor cannot guarantee your pregnancy and should especially not been used for birth control!

For couples who want children, it is important to know the ovulation, so they can plan and have sex during this timeframe of 5 days before the ovulation.

To help you predict these fertile days and your exact ovulation date in order to improve your chances of getting pregnant, we want to help you with this ovulation predictor. After entering your data and submitting the form your personal ovulation calendar will be displayed.

How do I calculate my average cycle length?

To calculate a more precise ovulation date, you will need your average cycle length. This requires you to keep track your cycle length for several month. The cycle length is defined as the first day of your period until the day before the next period (last cycle day).

The length may vary from woman to woman and cycle to cycle, but it usually lasts between 21 and 35 days (average = 28 days). So, if you do not know your cycle length right now, you should go with 28 days for now.
