Can you take Qining Progesterone Capsules at 40 days of pregnancy?

Patient's question:

No

Doctor's answer:

Progesterone is commonly used to treat threatened miscarriage and is harmless to the fetus. Generally, a gestational sac can only be seen on ultrasound after 40 days of pregnancy. If your period is usually delayed, it may not be visible even at 40 days, so you don't need to worry. If you have no other discomfort, you don't need to take medication.
