26 weeks pregnant, help

So I was in a car accident a week ago today, going 45 mph. And I've been getting sick, chest cold. I've been having a hard time breathing, stuffy, and sneezing quite a bit. Now I've been pretty good and doing my daily kegals. I try to do 30 a day. So idk why this is happening. But it feels like I can't control my bladder. Like yeah, I know when I sneeze and stuff it's common. But every once in awhile it'll just happen and it will get my undies wet. Should I call my doctor?
