Patient's question:
At 45 days pregnant, HCG still hasn't doubled, but today's ultrasound showed a fetal pole and fetal heartbeat. The ultrasound report indicated that the gestational sac is small. The doctor said that a small gestational sac can lead to HCG not doubling, and they are concerned about a potential miscarriage. However, they still prescribed progesterone and dydrogesterone capsules, and gave two HCG injections—one every other day. They asked me to return for a thorough check-up this Saturday. Could you please help me confirm this diagnosis online? Thank you.October 24th initial consultation: HCG 697.58 IU/L, progesterone 24.69 ng/mL
October 27th: HCG 2368.81, progesterone 18.67
Doctor's answer:
Early pregnancy hormone levels show pulsatile excretion, and the measured progesterone values fluctuate significantly, so the high or low progesterone levels have little guiding significance for clinical diagnosis. Clinical diagnosis commonly uses dynamic measurements of blood HCG levels to predict early pregnancy outcomes. During weeks 6-8 of pregnancy, HCG values should increase at a rate of 66% per day. If the growth rate decreases below 66% within 48 hours, it suggests an adverse early pregnancy outcome. Your HCG growth rate is slightly slower, so we recommend you follow your doctor's advice regarding medication and undergo irregular follow-up tests.
