Share 'one day past my "guess" date'

I know that it's only a guess.....sigh. Yesterday was my due date and today I'm still pregnant. I feel so wiped out and grumpy--not because I'm still preg. it's just that's how I feel. Well, maybe it is because I'm still pregnant.....? Any of you moms/midwives/doulas have some words of wisdom to share?
