And my friend the Physical Therapist Says...

Being that I've been running for years, I should be absolutely fine to continue through my pregnancy provided I take it easy and stop when it's no longer comfortable. She mentioned that one of her PT professors ran up until her 6/7 month of pregnancy when she had to stop due to a constant urge to pee every time she jogged and put extra pressure on her bladder! This made me feel better about my decision in the wake of my doctor's advice - thank you SS!
