I am 80% effaced n 3cm dilated only 33 weeks and 4days pregnant third pregnancy all 1yr apart given steroids for bbys lungs delivering soon? how soon?

Maybe not: Many women at 3 cm can last a few weeks. Especially since it's your 3rd pregnancy. Obviously, there's a chance you could deliver preterm, but there's also a chance you could go to term. That's good docs gave steroids. Watch for signs of labor and leakage of fluid, in addition to baby's fetal movement. No one can say when you'll deliver.... Hopefully it's at least 4-6 weeks from now!
