When preterm abortion is diagnosed rest should be taken and if the bleeding is caused by insufficient progesterone to maintain the embryo, oral birth control pills can be taken under the doctor’s supervision to preserve the fetus. The development of the fetus in the uterus should be monitored regularly during the period of fetal preservation, and fetal preservation should be given under dynamic monitoring. 4. If vaginal bleeding occurs and the bleeding is found to originate from the cervix, not from the uterine cavity, by vaginal examination, local treatment can be performed.
