Ultrasound examination of a 6-week pregnant fetus, how big is the fetus?

Patient's question:

No

Doctor's answer:

Hello, if the menstrual cycle is regular, generally at six weeks of pregnancy, an ultrasound examination can show a gestational sac of about 0.6 centimeters. Some can see fetal buds and fetal heartbeat. If there is vaginal bleeding or abdominal pain in the early stages of pregnancy, it is necessary to seek medical attention promptly.
