Whether or not low progesterone bleeding will preserve the fetus cannot be generalized and needs to be determined on a case-by-case basis. If the vaginal bleeding is heavy and the blood HCG continues to not rise or fall, the chances of keeping the baby are lower.
Progesterone is a hormone necessary to maintain pregnancy. Luteal insufficiency or abnormal thyroid function may lead to low progesterone, and some pregnant women will experience vaginal bleeding later in the pregnancy, which can lead to preterm miscarriage.
Luteal insufficiency can be treated with intramuscular progesterone 20mg once daily or oral progesterone preparations; hypothyroidism can be treated with small oral doses of thyroid tablets.
After the appeal is treated, if the vaginal bleeding stops and ultrasonography suggests embryo survival, the pregnancy can be continued, and most of the fetus can be preserved. However, if the clinical symptoms worsen, ultrasonography reveals a poorly developed embryo, and blood HCG continues to fail to rise or fall, it is likely to indicate that miscarriage is inevitable.
Pregnant women should seek regular medical checkups during pregnancy, and if low progesterone is detected, it should be corrected in time to avoid the development of preeclampsia that may lead to hemorrhagic symptoms with adverse consequences.
