If they cant stop your labor and you have the baby the chances of the baby being fine are really good. My sister had all 4 of her babies early 1 at 33 wks and the other 3 at 35weeks her last on was the only one that had to be in the nicu the rest all went home after 3 days
Well when I was 33 weeks they had to give me these meds through an IV to stop labor.
If you start labor this early the Dr will do what they can to stop it. Most only don't if you are 36 weeks or farther.
