well, not sure how encouraging my stats will be for you, but wanted to post anyway just to say that no matter what happens, it WILL be okay
My guys each so far have gotten progressively 2 weeks earlier. #1 was born at 36 weeks, no warning, just started having contractions in the morning, he was born that night. He was just under 9 pounds, so definitely ready to come out, and had no problems what so ever. He was home the next day.
#2 was born at 34 weeks, just under 8 pounds, same deal as #1 - no problems, home next day.
#3 was born at 32 weeks, after 10 weeks of bedrest for continuous preterm issues. He was in NICu for 3 weeks, needed some help breathing. He was 5 pounds when he was born
Now, #4 I've hit 31 weeks today - put on bedrest last weekf or some cervical changes (thinning and a bit of funnelling) But I have a feeling that he'll break our trend and make his appearance around 34 weeks.
Generally, the best predictor of having preterm issues is having had prior preterm issues (so, like me, if you've had several preemies, you're got virtually no shot of going to term, LOL!) BUT (and this is a big "but") it doesn't sound lke you had "preterm issues" you just had a baby who was done baking. there's a big difference between a babe born with no warning at 34+ weeks than a babe that you've been having preterm issues with for a while and with the help of medication and bedrest you've managed to keep in that long. Is it possible that you were off with your dates with your first?
