Quoting MommiesPrincesses:" I did read up on it .... It slows the contraction rate ur uterus has or something like that. I talked ... [snip!] ... newborn "acted funny" whatever that means... The way i look at it is whatever happens, happens natural.. Its all in gods hands"
I got those shots. THey are p17 shots. It's just progesterone really. It relaxes the uterus to help prevent contractions. This is going to sound mean, but if you think a 34 weeker was bad, try a 27 weeker. A 3 week NICU stay is hard, but if you end up with a very early preemie you can be looking at months long. My 2nd I had the shots and bedrest and he made it to term. No complications, no problems at all.
Look into the shot. The risks are VERY minimal since it isn't given until 16 weeks generally, then weekly after that. However, they have a really good success rate.
