Not seen yolk sac, embryo and heart tube

Patient's question:

Medical History: Last menstrual period on July 2, early sexual activity on July 13 and 14, and slight brown vaginal discharge discovered on August 13. First ultrasound examination at the hospital showed the following results: Uterine body size 69 x 69 x 55 mm, a 26 x 21 mm gestational sac observed in the uterine cavity, with no yolk sac, embryo, or fetal heartbeat detected within. A 5.7 mm wide, hypoechoic linear shadow was seen in the uterine cavity. The myometrium showed uniform echoes. CDFI revealed no significant abnormalities. Bilateral ovaries showed no significant abnormalities.
Past Treatment and Effects: First ultrasound examination at the hospital. Desired help: Please help analyze whether these test results are normal.

Doctor's answer:

Hello, under normal circumstances, you can see the embryonic stalk and yolk sac around 5 weeks of pregnancy, and the embryonic stalk and fetal vessel pulsation will appear around 6 weeks. Based on the information you provided, it is estimated that your pregnancy duration is short. Please wait and see for now, and follow up in one week. At this time, the examination is still too early, so the fetal heartbeat and embryonic stalk cannot be seen. It is recommended that you have a color Doppler ultrasound examination around the 50th day to confirm. Suggestions: 1. Maintain a relaxed mood and avoid tension and anxiety; 2. Pay attention to rest and avoid overexertion; 3. Abstain from sexual activity during the first three months of pregnancy. Wish you health!
