Polycystic ovaries usually affect the chance of pregnancy, but after pregnancy, the HCG value is the same as normal pregnancy and will not cause persistent low HCG due to polycystic. After pregnancy with polycystic ovaries, if the HCG is low, it indicates the chance of preterm miscarriage, so you should try to treat the pregnancy with birth control medication as much as possible, and check whether the HCG has doubled in 2-3 days. If the HCG does not double after medication, it indicates a preterm miscarriage, so you can only take oral medication to preserve the pregnancy to avoid a persistent decrease in the chance of miscarriage. The chances of getting pregnant with polycystic ovaries are relatively low, so you must pay attention to rest and not overwork.
