I had DS at 35 weeks too. He was breech, but they couldn't really give me a reason for the early delivery apart from a slight bruise on the placenta. I am now 30 weeks with DD and she is head down. Doc says there is no indication I will have her early so I have ELCS booked for 38 weeks. Have a sneaky feeling she will come early though so am having an early baby shower and getting her room ready in the next couple of weeks so I don't get caught off guard this time! Did they give you a reason for the early delivery?
