I'm Franco Kelly, and together with the Aula Ginecologia team, we prepared this video for you. We will provide a general summary of the changes that occur during pregnancy, from an embryological perspective. VISIT FRANCO KELLY'S CHANNEL:    / francokelly   Before I begin, I must make the following clarification: In clinical practice, gestation begins to be counted from the date of the last menstrual period or menstruation, and pregnancy is estimated to last 40 weeks or 280 days. In contrast, in embryology, days begin to be counted from the moment of fertilization, and pregnancy is said to last 38 weeks or 266 days. I make this clarification because confusion often arises. Embryology divides human prenatal development into three periods: 1. Pre-embryonic period 2. Embryonic period 3. Fetal period The pre-embryonic period covers the first three weeks of development. The embryonic period, depending on the literature you use, can begin at the end of the third week or from the fourth to the eighth week inclusive. And the fetal period extends from the ninth week until birth. VISIT OUR WEBSITE: WWW.AULAGINECOLOGIA.COM
