Patient's question:
How to calculate when you are pregnant? For example.Doctor's answer:
Usually, the calculation of pregnancy duration starts from the first day of the last menstrual period. However, in reality, the correct method should be—pregnancy begins when sperm and egg combine and implantation starts. This is when pregnancy actually begins. However, most people cannot determine the exact day of fertilization, as the day of intercourse does not necessarily correspond to the specific fertilization day. This is all normal. Ultrasound examinations are more accurate. The calculation of gestational age is an approximation, but there is no precise method to determine the exact day of conception.
