I actually rode all the way until 2 days before I delivered. Just got picky about WHAT I rode and HOW I rode as I went along. Made a deal with the husband & doctor that I would scale back or cut things as I felt my center of balance going. How lucky for me that it never did **hehehehe** Though the last 2 months I stuck to my steady-eddies & reliables. Spent the weekend before my induction attempting to get my water to break on its on by riding ~ my girls were taking bets on who was driving me to the hosptial when it did (didnt work). I may not have been able to keep food down for 90% of my pregnancy, but I sure as heck stayed in shape. Though I will admit that I think I got back in the saddle AFTER delivery a bit too soon (was back in the saddle working 9 days later - should have held off another week).
