Ovulation calendar online – calculate your periods and find out when you are most likely to get pregnant!

Calendar of ovulation is a convenient and easy-to-use service designed to calculate the menstrual cycle and the most favorable period for conception. Just set the first day of your last menstrual period and the usual length of your cycle (21 to 36 days) and this ovulation calendar will tell you which days in the next three months will be the most favorable for conception. At the same time, this online software calculates the so-called "safe days", or the days when conception is unlikely to happen. This way the ovulation calendar helps avoid an unwanted pregnancy without using any medication or mechanical contraceptives.

If you calculate ovulation online, the generated calendar will show you the probable sex of the child according to the day of possible conception. Such calculations are made on the basis of many scientific researches, which show that the probability of conceiving a boy is maximal on the day of ovulation and the day after. Also, there is a small chance to conceive a boy one day before ovulation. But the probability of conceiving a girl, on the contrary, is higher before ovulation.
