To account for the development of a pregnancy Objectively, although at first it seems weird, gynecologists and obstetricians prefer to calculate pregnancy for weeks, following the protocol of the Spanish Society of Obstetrics and Gynecology (SEGO). Thus, the first week of pregnancy begins to count from the first day after the last menstruation, so that the weeks of pregnancy begin to be counted two weeks before conception, moment that coincides with the ovulation of the woman.

The SEGO protocol maintains that the average duration of a pregnancy is 40 weeks, counted from the first day of the last period, since if we started counting from the moment of conception the pregnancy would last a total of 38 weeks and the data would be less objective. However, in addition to the weeks, we must take into account the division of pregnancy in trimesters, as each of them has specific characteristics in terms of training and development of the baby, health status of the pregnant woman and discomfort of pregnancy, and care guidelines and medical reviews.
