yes, it has begun.... i am only 22 weeks and i feel like i am going to jet out a little bit of wee when i cough or heave (which is unfortunately still happening from time to time) 
i am also at that stage where wind seems completely uncontrollable - it just leaks unexpectedly and sometimes noisily, thankfully, rarely smellily. i can be doing something as gentle as walking down the corridor at work and fart with every step 
and why is it i feel more
about the wind than the developing incontinence??
