Does progesterone intake affect the gestational sac in pregnant women?

Patient's question:

No

Doctor's answer:

At the beginning, progesterone is produced by the corpus luteum. After the placenta forms, progesterone is secreted by the placenta. Therefore, a temporary decrease in progesterone will not have any adverse effects, so you can rest assured. At this time, an ultrasound examination needs to be performed to check the gestational sac and whether the embryo development is normal. If everything is normal, you can relax.
