Calculator of Fertile Days and Ovulation

Calculator of fertile days

Getting pregnant is mostly a matter of opportunity since a woman can only get pregnant at the time of ovulation. The safe day calculator can be used to calculate all the duration of the ovulation cycles. Regardless of whether the cycle is regular 28 days or shorter or longer. Simply enter the date of the last menstrual period and the fertility calculator will show all fertile and infertile days in addition to the ovulation calendar.

With safe day calculator, you can calculate in just a few seconds what are the most fertile days of your menstrual cycle. If you are thinking of having a boy or a girl, follow the steps of the fertile day calculator and increase the chances of getting pregnant.

To begin, select the duration of your menstrual cycle in days from the ovulation calculator. Then, enter the very first day of your last menstrual period. Once ready, it will be calculated which is the most fertile day and also the week. These dates are indicative and can help you achieve pregnancy.

Remember that this calendar of ovulation and fertility is a tool based on statistics. Calculate the fertile days of a woman in menstrual cycles with averages between 21 and 35 days. If your cycle exceeds this date or you use a contraceptive method, the ovulation calendar is not suitable for you. Always check with your gynecologist.

How to recognize the fertile days?

The most important answer beforehand: no special tests or exams, nothing at all. And even with pregnancy computers that determine the temperature or composition of the cervical mucus, fertile days can only be determined approximately.

How does pregnancy work?

To get pregnant, the sperm in the fallopian tube must join with the egg. The most important date in this context is ovulation itself. The problem: ovulation cannot be determined with 100% accuracy. In a 28-day “sampling cycle,” ovulation is between the 13th and 17th day of the cycle. The problem is that very few women have a permanent cycle of the same duration at all times.

The sperm can survive 3 to 5 days; the egg itself can survive 12 to 18 hours. This means that the fertile days in a 28-day pattern cycle are between the 8th and 18th day.

On what day can you get pregnant?

The ovules can only be fertilized between 12 and 18 hours after ovulation. The sperm lives with 3 – 5 days much longer. In total, this results in a period of about 6 fertile days (the day of ovulation and the previous five days). Since it is not possible to determine the exact time of ovulation, it is necessary to provide some days of safety if you do not want to get pregnant.

The cycle

The length of the cycle is not more than the time interval between two cycles. The first day of the period is the starting of a new cycle. Unfortunately, only one point of the cycle can be easily determined: the beginning (due to menstrual bleeding).

Normal cycle length

There is no “normal” standard cycle. Each woman has an individual cycle, which can also vary from month to month. In addition, the duration of the cycle usually changes throughout life. Only very few women have the same duration of the cycle. On the other hand, irregular cycles are not a cause for concern, but they are considered normal.

Different long cycle

General statements about the cycle are difficult to make. On the one hand, this is because the periods of fertile and infertile days differ among women. On the other hand, the duration of a woman’s cycle also varies. Therefore, it is better than a calculation to observe the bodily signs to determine the fertile days – either by the doctor or through training.

The average duration of the cycle

Studies have shown that the 28-day cycle, which is said to be so frequent, is much rarer than expected. Only 12.8% of all cycles last 28 days. In addition, adult women are more likely to have a 28-day cycle than young women.

The most common duration of the cycle in women between 20 and 45 years of age is 27 days. By the way, all cycles between 23 and 35 days are considered medically normal. And another fact: Longer cycles are more frequent than shorter ones. So every 6th cycle lasts more than 33 days or even more. And each tenth cycle lasts 24 days or less. And five percent of the cycles of healthy women last more than 35 days.

Calculate fertile and infertile days

The fluctuations in the length of the cycle are completely normal. For subdivision into fertile and infertile days, a highly individual determination by the gynecologist is, therefore, more sensible.
