I was wondering if any of you ladies, have taken the progesterone shot (17 alpha-hydroxyprogesterone
caproate) after 20 weeks in pregnancy to prevent pre-term birth. My doctor wants me to take this shot, because I've had 2 premature babies, and I am already have complications with this baby. I'm almost 22 weeks now, and I have been trying to find some information on this shot, but I can't find anything for taking it after 20 weeks.
