Is it effective to take progesterone for threatened miscarriage at five months of pregnancy?

Patient's question:

No

Doctor's answer:

According to your description, it is not easy to determine this situation. At 5 months of pregnancy, it has already passed the natural miscarriage period. At this time, if there is vaginal bleeding, it is recommended to have an ultrasound to check for conditions such as placental abruption or placenta previa.
