A soft cervix is a good thing. You won't dialate if your cervix doesn't soften.
It means that your body is beginning to get ready for labor. But it doesn't mean that you will have the baby immediately. Remember that normal term is anywhere from 38 - 42 weeks, with 40 as the average. So you need about another 2 1/2 weeks and you're there.
Follow your doctor's instructions and do take things easy to keep baby in there for a few more weeks.
