Makena Injections (17P) (preventing preterm delivery)

Ri

I am pregnant with my second child we had our OB intake nurse visit where she informed us of the Makena Injections (also known as 17P) to prevent preterm delivery. I had HELLP Syndrome with my last baby and was induced at 35 weeks. Everything went fine but it could of been really bad. I wanted to know if there is any moms out there who did this and how it went? Thanks everyone
