Patient's question:
If the menstrual period ended on November 10th, and sexual intercourse was conducted on November 26th, but the period still hasn't arrived by December 10th, if pregnancy is suspected and a medication abortion is desired, should the date of conception be calculated from November 10th or from November 26th? (Sexual intercourse was the first time. It has never happened before.)Urgent!
Doctor's answer:
The exact date of conception is difficult to determine. Clinically, the first day of the last menstrual period is generally considered the start date of pregnancy. It is hard to determine the exact day of conception for a pregnant woman. The gestation period is approximately 280 days. When calculating the date of pregnancy, it should be counted from the first day of the last menstrual period.
