Progesterone pills in pregnancy

sierra • Mother of a 10year old(rainbow), and a 5 year old (rainbow), and an angel baby girl❤ (lost my pot of gold, furthest loss for me), Rainbow babygirl due in May.

Has anyone taken these? My dr called in a script for these and baby aspirin yesterday. They have some extra testing they need me to do in a week as well. I've never had to take this during pregnancy before but was surprised you have to insert them vaginally, 3 of them. I woke up last night to tinkle and one plopped out. 🤦‍♀️ Anyways, if you've taken them is there any side effects you've experienced? Thank you 😊
