How to determine the date of conception

Now some married couples are trying to accurately calculate the date of conception. The reasons for this are different for everyone. Some want the birth of a child of a certain gender, while others even want to plan the fate of their child, believing in the predictions of astrologers. In any case, it will be useful to know exactly when this event occurred.

Why determine the date of conception

The day when the male and female germ cells join in the body of the expectant mother, and is called the date conception... In fact, fertilization does not always take place on the very day of sex. The fact is that sperm retain their ability to fertilize for another three days after they enter the woman's body. The egg cell also does not always mature at the same time. Therefore, it is very difficult to accurately indicate the date of fertilization.

Knowing this date greatly simplifies the determination of the gestational age. By the date of conception, the doctor can more accurately determine the estimated date when the baby will be born. In addition, this date will help to more accurately determine the period for passing the necessary examinations and tests during pregnancy. If the time of conception is precisely known, the expectant mother can immediately begin to eat properly and take care of her health, since the fetus is still very vulnerable in the first weeks of pregnancy. In addition, by the date of conception, you can try to establish the sex of the future baby.

How to calculate the date of conception

Surprisingly, but most accurately the date of conception can be calculated only after the baby has already been born. Medical research suggests that birth toddler in the overwhelming majority of cases occurs on the 266th day after conception. Therefore, you just need to count this number of days from the date childbirth back.

You don't have to do the calculations yourself, but just use one of the many online services that offer such a service. You just need to enter the initial data into a special calculator and in just a few seconds the system will itself determine the fertilization date. The calculation takes into account the start date of the last menstrual period, as well as the duration in days of the menstrual cycle.

Another calculation option is to use ultrasound data. As a rule, this can be done as early as the tenth week of pregnancy. Here it will also be necessary to take into account the day of the beginning of the last menstruation and the duration of the female cycle. Difficulties can arise if a woman does not remember the start date of her period or if she has an irregular cycle. Therefore, it is very important to track and record these metrics.

Determine the sex of the child by the date of conception

There are several ways to determine the sex of the unborn baby. One of the popular methods is based on the knowledge of the day of fertilization of the egg. Any woman knows that fertilization occurs only on certain days of the cycle. These days include the day of ovulation, two days before and two days after. Therefore, it is possible to calculate the sex of the baby if we take into account the peculiarities of the X and Y chromosomes.

Medical research suggests that sperm with X chromosomes move slowly but are more resilient. They retain their functions for up to 4 days after sex and can wait until ovulation occurs. Spermatozoa carrying Y-chromosomes are highly mobile, but less resilient.

Therefore, if sexual contact occurs a couple of days before ovulation, then with a high degree of probability your future baby is a girl. If you had sex on the day of ovulation or immediately after, then most likely you are expecting a boy.
