premature lab
"I delivered my first child at 36 weeks after having preterm labor at 29 weeks. I had a partial amniotic rupture with that preterm labor and I was dilated to a 4 when they finally stopped the contractions.

I am currently 28 weeks pregnant with my second child, and I have been on weekly
Makena injections since week 16. I began having closely spaced contractions yesterday and went to my local hospital. My cervix was still closed, but the frequency of the contractions and the lack of their response to the Magnesium bolus caused them to send me by ambulance to a more prepared hospital in a larger city. 

I'm home today and not in the hospital. I know it's because of the Makena shots! Without them my cervix would have been dilating no doubt."
