If only us runners could utilize the power of the uterus! Man, that muscle is strong. Thanks to its powers, I'm 80% effaced and at 1 cm. ;) There was one night last week at work when I was convinced my uterus was pulling in and down so hard that it was going to wrap my body up into a ball! I could barely walk! (luckily there wasn't any sharp pain associated though) My coworkers kept touching my belly because it was so tight... I joked about my amazing one pack....to think of the strength! |
