I went into preterm labor with my last baby and delivered at 35 weeks. While he was perfectly fine that is not always the case. My OB started me last week (16 weeks gestation) on 17P injections. I was just wondering if anyone else has used it and had a good outcome? I have seen lots of succesfully studies, etc. Just looking for personal experiences I guess. My OB is now placing all of his patients who have delivered before 37 weeks on this therapy and said it's had very promising results.
