Re: Anyone gone into labor without many signs it was coming?
With DS2, I had no indictations that he would be coming, before actually going into labor. I saw my midwife at 39 weeks, and she did an exam - I was dilated to a 3, and had been since 36 weeks, so no big deal there. I hadn't had any contractions at all, other than Braxton Hicks, and those had actually stopped around the 34-35 week mark.
I got my first contraction around 4pm when I was 39 weeks+2 days along, and DS2 was born the next morning, at 1:51am. I never had any contractions before that, or had the bloody show. Both the midwife and I actually expected him to come "late".
