When does pregnancy start from the day of menstruation?

Modern women have a better understanding of physiological behavior, because in order to successfully achieve pregnancy, they must properly grasp their own physiological characteristics, which is one of the basic conditions for women to become pregnant. In order to calculate the pregnancy period, pregnant women need to know the specific pregnancy time, among which menstruation is the most important reference. Let’s take a look at which day of menstruation does pregnancy start from?

1. Count from the last menstrual period. The more accurate calculation of pregnancy days is from the first day of the last menstrual period, not from the day of intercourse. For example, if the first day of the last menstrual period is March 1st and it lasts until April 10th, the pregnancy days are 40 days.

2. Count from the time of conception. From the perspective of embryology, that means subtracting fifteen days from the number of days obtained by the above calculation method. This is the actual time of conception. Because this time is the actual ovulation period, but this algorithm is only limited to women with regular menstruation. If your menstrual cycle is irregular, it is best to use the first method.

Some female friends may get pregnant soon after preparing for pregnancy, which is a very happy thing for them. In fact, your doctor will help you calculate these during the first prenatal check-up. Of course, you can also roughly calculate it yourself. It is better to remember them clearly than to be confused.
