Patient's question:
I had my period on February 18th, and I've been amenorrheic for 46 days. The pregnancy test showed a faint positive. On April 1st, the ultrasound couldn't detect a fetus. On April 2nd, my blood HCG level exceeded 818. There was no bleeding, no abdominal pain, but I did have some lower back discomfort.Doctor's answer:
Your last menstrual period was on February 18th. Therefore, by April 1st, the duration of amenorrhea is 42 days, which is equivalent to 6 weeks of pregnancy. Normal blood HCG levels at 5-6 weeks of pregnancy should exceed 850,208,003 (mIU/ml). Currently, your HCG level is only 818, and the early pregnancy test shows a weak positive result. There has been no visible gestational sac on the current color ultrasound, and there is a need to consider the possibility of an ectopic pregnancy. Although the typical clinical symptoms of ectopic pregnancy are abdominal pain and vaginal bleeding, when the blood β-HCG level is greater than or equal to 18 kU/L, a vaginal MRI should be able to detect the echo of the gestational sac. If no intrauterine gestational sac is observed, there should be a high degree of suspicion regarding the possibility of an ectopic pregnancy.
