Hello LondonLady,
You really need to consult with a Physician. Your symptoms could be due to just about anthing. It's impossible for you to figure out what may or may not be wrong based on question/answers on a message board. We are unable to do tests and evaluate a person.
The most common for urinary incontinence in women is stress incontinence.

But, there is no way for you to know without Drs. and testing.
