Baby-On-Bladder....

KristinandMike05

Hey all!  I'm 22 weeks preggo (this is my first pregnancy) and next weekend I am running a half-marathon.  I've been cleared by my doctor and all that good stuff.  My only problem is that apparently someone has taken up residency on my bladder. Do any other active moms-to-be out there have any tips to help me get through the 13 miles?? Is there anything I can wear or do that would make this easier? I don't want to bail just because I feel like I have to pee all the time. I could really use some advice!
