How to calculate ovulation period for pregnancy

There is a widely-known myth, especially, among women that cannot get pregnant that the 14th day of the cycle is the most fertile day, but it is actually false. Recognizing fertile days without special tests or additional examinations is not possible. Pregnancy computers determining the temperature and consistency of cervical mucus are not the most precise way to determine the fertile days as well.

To identify a safe period, different methods can be used. The ovulation calculator is one of the most popular ways aimed at identifying the evaluation period, fertile and infertile days and the length of each cycle. When using an ovulation calculator, you need to enter the latest date of menstruation, and the ovulation calculator will show the ovulation and safe period. The ovulation calculator cannot be used alone as a natural birth control method but as the results can be influenced by different external factors.

To avoid any unwanted pregnancy, it is better to use the ovulation calculator with other methods like the symptothermal method, calendar method, and other.

Using an ovulation calculator for pregnancy, one can easily calculate ovulation, fertile days, and infertile days:

  • calculate the fertile days when it is possible to get pregnant
  • calculate infertile days, safe days/safe period when it is not possible to get pregnant
  • calculate the luteal phase, a period when it is possible to conceive a baby
  • calculate when a pregnancy test is possible

The safe period calculator can be used by women whose average length of the menstrual cycle from the past six months is between 25 and 35 days. Also, variation between the shortest and longest cycles should be no more than 7 days. Be sure to consult your doctor to use this natural birth planning method. The approximate failure rate of using an ovulation calculator is about 3 to 4%.

When using the calculator after childbirth, this method can be applied only after 6 regular menstrual cycles to get the exact results. Teens and women reaching menopause cannot rely on this method.

Given the fact that the fertile period doesn’t begin with ovulation, you can also try to conceive during six days before ovulation.

A woman is considered “unable to conceive” only after two years of unprotected sexual intercourse. If you were able to get pregnant, you could use the ovulation calculator to determine the day the baby will be born.

Becoming pregnant is possible if spermatozoid unites with the egg. It takes place in the fallopian tube. For this purpose, the best time to get pregnant is the ovulation period that lasts from 3 to 5 days which are between the 13th and the 17th day. At this period, the ovulation occurs, and one or more eggs are released from the ovary. The thing is that the egg can survive only from 11 to 19 hours. However, the ovulation period lasts about 6 days when a woman is fertile. It includes the day of ovulation and 5 days before it.

The beginning of the menstruation is considered the beginning of the menstrual cycle. The first 5 days of the period are relatively infertile. However, this is true under the condition that there are no hormonal influences and that ovulation occurred in the previous cycle. The sixth day of the menstrual cycle is considered possibly fertile. When the menstruation is finished, there will come a few days before the ovulation period. After ovulation, the luteal phase starts.

Every woman who is trying to get pregnant should remember that one cannot be 100% sure ovulation occurs or not. Another problem is that not many women have regular cycles. If the whole cycle lasts between 22 and 35 days, it is considered normal. Short cycles are not very common while longer cycles are often observed in women. The most common cycle length in women is 28 days.

The menstrual cycle length is, to put it simply, the interval between the two cycles. A new menstrual cycle begins with the first day of menstruation. The beginning of the cycle is the only point in the cycle that can be easily determined without additional methods and equipment which cannot be said about other points of the menstrual cycle.

Women also need to understand that there is no such a thing as a normal cycle length. Every woman has a unique cycle that sometimes even fluctuates from month to month. Moreover, menstrual cycle length can vary throughout life. In case, your cycle length is varying, observe all the changes in your body caused by taking medicines, stress which can postpone the ovulation and compare them with other indicators. If you face any difficulties with consultation, you can ask the gynecologist to determine your fertile and infertile days.

How to calculate ovulation period with calendar

Getting pregnant depends on many factors. The best way to get pregnant quickly is to make love regularly. Also, every woman needs to visit her gynecologist regularly. A healthy diet is also hugely important to improve the chances of getting pregnant. Sometimes, women cannot get pregnant even during a few months having a healthy diet because the chances of getting pregnant that depend on the diet are only 20 percent.

Stressing out over getting pregnant which makes pregnancy even less possible, try to avoid stress and enjoy your life. Doing physical exercises is also a good way to prepare your body for pregnancy. Remember to get a lot of fresh air every day.

Getting pregnant also depends on the proper timing. This is the truth that every woman can become pregnant during the period of ovulation. One of the most popular methods to calculate the ovulation period is a calendar method. The calendar method or the rhythm method is named after doctors Knaus and Ogino. In this method, information is obtained mathematically. It is important to remember that you cannot rely on the results of this method if you use an ovulation calendar less than 6 months. The calendar method is actually not considered 100% reliable because it neglects bodily signs (temperature and hormones).

Using the calendar method, you need to mark the mucus patterns every day. Once you have the periods of the menstrual cycle including dry days, sticky days, wet days and slippery days marked on the calendar, you can plan or predict pregnancy based on the current and past cycles. The mucus is different at every stage. If you don’t understand the pattern, ask your gynecologist to help you. The symptothermal method, using pregnancy computers and ovulation tests are considered better methods which measure ovulation, using daily waking temperature, hormone levels, and/or cervical mucus analysis.
