Lately, every time I run, I tend to get BH contractions during/after my run. Doctor said it is a heat/dehydration issue. Despite running on the treadmill and drinking TONS of water, it still seems to be an issue. Given I was put on bed rest at 34 weeks with my first due to low fluid (and I was not running at all!), I think I may just have to stick to walking for the remainder of this pregnancy:( Was really hoping to run throughout the entire pregnancy but the heat is challenging (even early in the morning) and don't want to risk the health of my baby or myself. I figured, I will be back into running by late fall:) Just in time for cooler weather running!
