explanation of ticker on right side of blogs

If you are a counter of weeks and know that the due date comes at 40 weeks and have noticed on my ticker that it doesn't quite add up it is because it is counting how many weeks and days we are so far and then how many days until scheduled c-section which is 36 weeks and 2 days. Here is hoping we make it that long, but if we don't we are praying for short stays in hospital and three healthy babies!!! Only a week left and we are at 34 weeks which means we can stay in Eau Claire, so here is hoping for a fast and uneventful week ahead!!!
