What all conception calendars are based on

The best time to conceive a child is the day when the egg matures and passes from the ovary into the fallopian tube. This process is called ovulation. If during this period the mature female reproductive cell is fertilized by the male reproductive cell, it means that conception has occurred.

Otherwise, an unfertilized egg is released during menstruation.

All calendars are based on the fact that the male reproductive cell can live in the female body for up to five days… Based on this, one can understand that fertilization can occur several days before the onset of ovulation and several days after its end.

The release of the egg from the ovary occurs in the middle of the menstrual cycle. You can get pregnant not only during ovulation, but also on fertile days. That is, 3-4 days before ovulation – and 2 days after it. Based on this information, you can track the successful period for trying to get pregnant.

For example, if a girl’s cycle is 30 days, then this number must be divided by two. It turns out 15, this suggests that on day 15 the egg leaves the ovary, which means that 12, 13, 14, 15, 16 and 17 days are the most favorable days for planning pregnancy.

Such calendars are used not only for planning pregnancy, but also to prevent it… In the female menstrual cycle, there are so-called “dangerous” and “safe” days. Dangerous days are the day of ovulation, a few days before and after it. For those who are not yet going to have a baby, it is better to give up sexual intercourse these days or take a responsible approach to contraception.

A few days after menstruation and a few days before they start are considered safe. For example, if a girl’s cycle is 30 days, then 1-10 and 20-30 days of the cycle will be safe.

Note! Safe days can only be relied on by healthy girls with a regular cycle without the slightest deviation. And yet, even so, this method cannot be guaranteed to protect you from an unplanned pregnancy.

Using a personal calendar to determine the date of conception

In order to accurately determine the days suitable for conception, a woman must have her personal calendar. It can be wall or pocket, the main thing is to regularly mark the days of the beginning and end of menstruation. To accurately determine the days of ovulation, ideally, you need to keep such records for at least one year.

Personal conception calendar

When you have been keeping a calendar for a long time, you need to analyze all the data in it:

  1. First you need to determine the longest and shortest cycle of all time.
  2. Then subtract 11 from the longest, and subtract 18 from the shortest. For example, if the longest cycle of a girl lasted 35 days, subtract 11 from it and get 24. This means that day 24 is the last day of the fertile phase.
  3. To determine the first day of the fertile phase, you need to subtract 18 from the shortest cycle, for example, 24 days.
  4. We get the number 6 – this day will be the first day of fertility.

Based on the above example, we can conclude that the probability of getting pregnant will be high from 6 to 24 days of the cycle. You can easily calculate this information yourself by simply replacing the given values ​​with your own data.

In addition to the calendar method, you can calculate favorable days for pregnancy by regularly monitoring the basal temperature in a state of complete rest. It is necessary every day at the same time (preferably in the morning) to measure the temperature in the rectum and record the data. Ovulation occurs the day after the day when the body temperature was at its lowest. When the body temperature rises to 37 degrees and above, this indicates the saturation of the body with progesterone, that is, the onset of ovulation.

Note! Rectal body temperature measurements may be inaccurate if you are sick, have bowel disorders, or have recently consumed alcohol.

Lunar calendar of Jonas-Shulman

This calendar was used by women many generations ago. There are several phases of the moon, and each person was born in a specific phase. If you believe this method, a girl has the greatest chance of getting pregnant exactly in that phase of the moon, which was before her birth. In addition, the Jonas-Schulman lunar calendar contributes to a favorable course of pregnancy, preventing the risk of miscarriage, abnormalities in the development of the child, and so on.

The creator of this method explained his theory by the fact that girls in ancient times ovulation occurred just at the time when the moon was in the required phase. That is, if you correctly use the usual conception calendar, in parallel with the lunar calendar, you can most accurately determine the appropriate day.

To use this method, you need to know what phase the moon was in on your birthday. The time zone plays an important role, therefore, for the calculation, information is needed about the woman’s place of birth, and the planned place for conception. In his works, the doctor wrote that using his method, you can even plan the desired gender of the baby.
