How about all of those commercials for the medication to calm down the "gotta go" urge? I can't recall the name, but the pharmaceutical advertises pretty heavily.
What you're experiencing (Sandra) could be a combination of irritable bladder, which is common I think, coupled with having given birth. Most women (who've delivered vaginally, especially) experience at least a little leakage from time to time with sneezing, etc,
My daughter was born with a kidney defect. She was missing a valve in her ureter between the bladder and kidney, so she had reflux and would get terrible kidney infections. as once urine gets into the bladder its no longer sterile, but then it would flow back into her kidney. It was eventually was repaired surgically, but for the first few years of her life, (after her doctors finally figured out what was wrong!) she took an antibiotic and also a medication like the one I referred to which is being marketed now, daily. I remember one time I was standing in the bathroom, filling a glass so I could give her her pills (she could take pills by age 2, quite impressive, right? ) Anyway, you know how its so easy operate on autopilot? I fill the glass, I've got the pills in my hand, and so I swallowed them. It was an oops moment.
