TMI bladder issues

Netty_3

Ladies that had a vaginal birth...are you having a loose bladder?  It's like I'm still 6-9 months pregnant the way my bladder is. I find if I sneeze or cough I may tinkle a little.  It came to a head when I was at the gym in a class and we started doing jumping jacks...apparently too much focus on other parts allowed a little to leak. 

 Anyone have advice on what can be done? Really want to avoid another embarrassing moment.
