How to Count the Weeks of Pregnancy

A very common question for many pregnant women or not, is how to count the weeks of pregnancy, even if they have regulated cycles. Another doubt, too, is to count the pregnancy, just by the hormone HCG , which is detected by the blood test. But counting the weeks of pregnancy is not that complicated. But we can say that it is also not so easy to understand. Therefore, an explanation of how to count the weeks of pregnancy and also the probable date of birth of the baby, can become a real saga and tie knots in the head.

Counting by Menstruation Day

The pregnancy is 280 days or 40 weeks right? Then we will count the weeks of pregnancy from the first day of menstruation . It seems strange I know, but it is the way that doctors know exactly how to count the weeks of pregnancy, in a way that the baby is born at the right time. So to do the calculation with the doctor you must think and answer: My last period was day?

But it is not so with all women, there are cases that counting the weeks of pregnancy by menstruation can be totally wrong, either by delay or even because the woman does not remember the day she menstruated or even by her calculations she menstruated even when pregnant .

IMPORTANT: If, over the months, the ultrasound indicates that your baby has measurements and weight above what is indicated in the prenatal calculation, do not be alarmed. Ultrasound is an estimate and may vary in information.

When Does HCG Appear in the Blood?

HCG begins to appear in the woman’s body after nesting , and then the tests, both in the pharmacy and in the blood, start to be positive with amounts above 25mUI. In some laboratories, just over 50 MIU is considered positive . However, still very early in pregnancy, the hormone may be very low. About 20, 50, 100mUI. These amounts may seem low, but it is normal to do this if you take the exam too early.

There are some tables of HCG levels on the internet, however, none of them can estimate with absolute certainty and answer the famous question of how many weeks of pregnancy the woman is. They can only give an estimate. That’s because the body can secrete more or less HCG. Detection may differ from woman to woman, precisely because it may depend on hormonal variation and number of babies.

Is the amount of HCG for Gemini greater?

So if they are twins, the tendency is to be in greater quantity, however, it is not a rule. The reference tables of the laboratories can also be the most varied and can be confusing or even frightening because they can be for more or less than what was given in the exam. Therefore, determining how to count the weeks of pregnancy using HCG is not the best way. The date of the last menstrual period makes all the difference in this account. But what about those who do not remember what day they menstruated?

For women who are suffering a lot from the nausea and nausea of ​​this phase and find it very difficult to swallow the vitamin, there is a great option, the FamiGesta vitamin  It consists of all the important vitamins for this phase with the difference in the size of the capsule, which is much easier to swallow. You can buy it here in our online store.

Pregnancy Weeks – How to Get the Exact Account?

For those who want to know what weeks of pregnancy they are in and do not remember the day they menstruated, an ultrasound is needed . The doctor can order the first ultrasound and this can accurately determine the gestational age, stage and weeks of pregnancy that the woman is. The sooner, the better to know. But always after the 5th week of pregnancy, you can already have an accurate calculation to know how many weeks of pregnancy the woman is and the date of birth.

All this due to the size and weight of the baby that can start to change after a period and then, it is suggested that the bigger the baby (the earlier the stage of pregnancy) the greater the chances of being incorrect or giving a huge difference in the date of birth . These wrong measures favor mistakes made by the dpp (expected date of delivery).

How to confirm?

In short: if you are regulated and have a correct menstruation, the date of the last menstrual period is used to know how many weeks of pregnancy you are. But if you are unregulated or do not remember the date of your last period, then ultrasound is the best way to count the weeks of pregnancy . Also to know that the ultrasound after a certain period of gestation, can give a variation in the date of birth. So, you should really consider the date of the first ultrasound.

Questions from Readers:

Is it possible by ultrasound to see the weeks of pregnancy?

Yes, the ultrasound exam is indicated at the beginning of pregnancy to confirm the gestational weeks, in addition to being able to confirm whether the development is within the expected. During pregnancy, ultrasound cannot be taken into account for weeks of pregnancy as the baby’s development, growth and weight gain may vary from pregnancy to pregnancy.
