Patient's question:
Can blood tests and ultrasounds accurately determine the number of days of pregnancy? Because I forgot when my period came, and I've been pregnant for a while! Are blood tests and ultrasounds accurate??Doctor's answer:
The duration of pregnancy is typically calculated from the first day of the last menstrual period in medical terms. The estimated due date also starts from this day, and 280 days of pregnancy is considered the full term. It is not necessary to calculate the specific time of intercourse or conception. As long as pregnancy is confirmed, the calculation of pregnancy duration begins from the first day of the last menstrual period. It is best to visit the hospital for prenatal check-ups as early as possible to determine the exact pregnancy and due date. The doctor will provide accurate results based on the examination. I hope my answer helps you, and I wish you a smooth pregnancy.
