Being overweight sort of means it takes longer to feel sometimes, but its not a problem.
By the way, I had another normal birth (induced for the 4th time though, due to GDD and pre eclampsia) and it was the same as the other 3, almost identical. No dramas. GDD and high BP have both disappeared now too, which is good.
I think as long as you are healthy, then being a bit overweight is not a big issue - there are more serious things to be concerned about I think.
