Jessica,
I'm a pediatrician/intensivist - just a few words to encourage you to relax and not worry. If you're 33 wks and closed, you and the baby should be fine, especially since you know your doctor has given the ok. Risks to little babies born at 32 weeks and older is really pretty low in this day and age - most of the time, they just need some time to 'catch up' with weight gain. Taking good care of yourself, trying to relax and enjoy the time will be the best thing you can do for your little one still cozy inside. Hope this helps - keep us posted!
