A low human chorionic gonadotropin (HCG) level in pregnancy is considered to be the result of an ectopic pregnancy or a delayed development of the gestational sac. A low human chorionic gonadotropin level needs to be evaluated in conjunction with the progesterone level. If the progesterone is also low, the chances of miscarriage increase. It is important to seek medical attention during this period to alleviate the hormonal imbalance that is causing the low values. During this period of time, you should also pay attention to bed rest, do not strenuous exercise, prohibit sexual intercourse, and enhance nutrition in moderation. Pay attention to monitoring the changes of the gestational sac, fetal heart and buds.
