Pregnancy week 1: pregnancy starting point

With this post we start ourPregnancy Special week by week, starting withweek 1 of pregnancy, in which we will take a fascinating journey through the gestation of the human being from the moment of conception to the day of birth.

The approximate duration of pregnancy is280 days of gestation, or what is the same38 weeks from the moment of fertilization of the ovumand40 weeks from the date of the last menstruation (LMP) .

As in most women it is not possible to calculate theexact day of ovulation, the first day of the last menstrual period is taken as thedate of the beginning of pregnancy.40 weeks from that date are counted tocalculate theprobable duedate.To know it, you have to subtract three months and add seven days to the first day of the last menstruation.

Estimated due date

The first day of the last period is the one that marks the beginning of the pregnancy.Therefore, if you look in this table that day, in the line below you will find thecorrespondingprobable delivery date.

Anyway, it is an estimated date.A very low percentage of births occur on the expected day.

Here is a table with which you can find out your probable due date (FPP). You have to identify in the bold line (the one that begins with January, February, etc.) the first day of your last menstruation and the month.The number that appears right on the bottom line is the due date for the month indicated on that same line.

Week 1 of pregnancy

Thefirst week of pregnancyyou are not actually pregnant yet, sinceduring that week you will have your period.

Vaginal bleeding occurs caused by the desquamation of the functional layer of the endometrium that has been prepared to house the fertilized egg.As there is no fertilized ovum, menstruation occurs.

It is the pre-ovulatory stage, variable from one woman to another, which begins with the first day of menstruation.

Women with irregular cycles

The female cycle lasts approximately28 days, but 90 percent of women have cycles between 23 and 36 days.There are women who even have longer and variable cycles from one month to another, therefore it is very difficult to calculate the moment of ovulation and even more so the weeks of pregnancy.

A woman who has her period every 47 days will not have the same weeks of pregnancy as one who has it every 23 days, for example.There may be weeks of difference between one and the other, therefore the due date of the first will be after week 40.

Even so, the first day of the last period is taken as the starting point of pregnancy, but in reality the gestation time can only be calculated more accurately through ultrasound measurements.

Prepare to get pregnant

If you are looking for pregnancy, you should be taking afolic acid supplement forat least one month beforebecoming pregnant, to avoid defects in the baby’s neural tube, the basic structure of the nervous system, which is formed in the first weeks, even earlier. that you find out that you are pregnant.

It is also important that you take care of your diet and of course, stop smokingandalcohol, habits that are totally harmful for your baby.Nor should you take medications, unless they have been specially indicated by the doctor, knowing that you are trying to get pregnant.Of course, not drugs either.

Both women and men should lead a healthy lifestyle, as well as reduce anxiety levels both at home and at work.Being healthy when conceiving will make you have a healthier and safer pregnancy.
