Usually, gravidas is detected when the pregnancy is about 2 months old. This is because pregnant women with hyperemesis gravidarum have a higher blood HCG than other pregnant women and experience irregular vaginal bleeding and an abnormally enlarged uterus at about 2 months of menopause, and after ultrasound, no gestational sac is found within the uterine cavity, there are no buds, and there is no primordial cardiac tube pulsation. Only grape-like structures are found in the uterine cavity, and blood HCG tends to be significantly higher than blood HCG in the same gestational week, even up to 100,000 units in some cases. In this case, it is recommended that the uterus be cleared promptly and the tissue removed be sent for pathologic examination in order to understand whether it is a benign or malignant hyperemesis gravidarum.
