Discouraged

So I'm 37 weeks today and for the past couple weeks I was sure the baby was coming any day. I've been extremely uncomfortable, having contractions, barely able to walk because of baby's position. Today, I feel better than I've felt in weeks. I swear the baby must have moved up instead of down. WTF? My first 2 were early and I'm just convinced this one is going past the due date and will end up being 10+ pounds (she was 7 lb 2oz at my 36 week ultrasound).
