Conception is the moment that marks the first day of gestation and occurs when the sperm manages to fertilize the egg, initiating the gestation process.
Although this is an easy time to explain, it is quite difficult to try to figure out what day happened, as the woman usually has no symptoms and may have had unprotected relationships in other days close to conception.
- Thus.
- The date of conception is calculated as a 10-day interval.
- Which represents the period in which the fertilisation of the egg should have taken place.
There are two main methods for calculating the design period
To find out which days you may have become pregnant, enter the date of the first day of your last period:
The design usually occurs 11 to 21 days after the first day of your last period. Thus, if the woman knows what the first day of her last period was, she can estimate a 10-day period during which conception may have taken place. To do this, add 11 and 21 days to the first day of your last period.
For example, if the last period appeared on March 5, it means that the design must have taken place between March 16 and March 26.
This technique is similar to the calculation that uses the date of the last period and is used, in particular, by women who do not remember the first day of their last menstruation. Thus, thanks to the date estimated by the doctor for childbirth, it is possible to know when it might have been the first day of the last period and then calculate the time interval for conception.
Generally, the doctor estimates childbirth for 40 weeks after the first day of the last menstrual period, so if you take those 40 weeks off on the likely date of delivery, you get the date of the first day of the last period before pregnancy. With this information, it is possible to calculate the 10-day period for the design, adding 11 to 21 days to that date.
For example, in the case of a woman whose scheduled due date is November 10, it takes 40 weeks to discover the possible first day of her last period, which in this case will be February 3. To date, we must now add the 11th and 21 days to discover the 10-day interval for the design, which was to be between February 14th and 24th.
