Share Pregnancy Week 1
Lola Rovati @Lolarovati
We start with this post to our Special Pregnancy week by week, starting with week 1 of pregnancy, in which we will make a fascinating journey through the gestation of the human being from the moment of conception until the day of birth.
The approximate duration of pregnancy is 280 days of gestation, or 38 weeks from the time of fertilization of the ovum and 40 weeks from the date of the last menstruation (FUM) .
As in most women it is not possible to calculate the exact day of ovulation, the first day of the last rule is taken as the date of beginning of pregnancy . To calculate the date of delivery 40 weeks are counted from that date. If you want to know your probable date of birth 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 pregnancy. Therefore, if you search in this table that day, in the line below you will find the corresponding probable date of delivery .
In any case, it is an estimated date. A very low percentage of births occur on the expected day.
Pregnancy week 1
The first week of pregnancy you are not pregnant yet, because during that week you will have the period.
Vaginal bleeding occurs due to the desquamation of the functional layer of the endometrium that has been prepared to accommodate the fertilized ovum. Because there is no fertilized egg, menstruation occurs.
It is the preovulatory stage, variable from one woman to another, which begins with the first day of the period.
Women with irregular cycles
The female cycle lasts approximately 28 days, but 90 percent of women have cycles of between 23 and 36 days. There are women who even have longer and variable cycles from one month to another, so it is very difficult to calculate the time of ovulation and even more weeks of pregnancy.
A woman who has the period every 47 days will not have the same weeks of pregnancy as one who has it every 23 days, for example. There can be weeks of difference between one and another, so the delivery date of the first will be after week 40.
Even so, the first day of the last menstrual period is taken as the starting point of pregnancy, but in reality the gestation time can only be calculated more accurately by means of ultrasound measurements.
Prepare to get pregnant
If you are looking for pregnancy, you should be taking a folic acid supplement from at least one month before becoming pregnant, to avoid defects in the neural tube of the baby, basic structure of the nervous system, which is formed in the first weeks, even before You know you're pregnant.
It is also important that you take care of your diet and, of course, quit tobacco and alcohol, totally harmful habits for your baby. Also, you should not take medications, unless they have been specially indicated by the doctor, knowing that you are looking to get pregnant. Of course, no drugs either.
Both women and men should lead a healthy lifestyle, as well as reduce levels of anxiety both at home and at work. Being healthy at the time of conception will make you have a healthier and safer pregnancy.
