I'm currently doing the Makena injections once a week. I started them at 16 weeks.
I took 17 hydroxyprogesterone with my son, but they can no longer mix the compound. It has to be the Makena now. I'm 22 wks and start Monday, my insurance took forever to approve. I was reading some risks of miscarriage and stillborn. Kinda scary.
I am currently on them now once a week. I haven't had any side effects and will continue the shot until 36 weeks.
