This is quite grim, but I've not told anybody yet and I really feel the need to share. (DH and DD are away, all my friends and family are away, I'm home alone, can't tell my colleagues at work).
I'm 28 weeks, I have a catarrh-cough / cold. Slept really badly this week as as soon as I lie down I start coughing myself sick. Also coughing lots during the day. Every time I cough, if I've not very recently emptied my bladder, I wee a little bit. I have to try to run to the loo to do a wee first while holding in the coughing fit, which doesn't always work. I work in comms for a big int. organization and am covering meetings all week, so have been darting out of meetings/conferences (can't take time off without it being really bad for my team).
Yesterday I walked briskly out of a meeting (over 60 people in it, I wasn't speaking) to the loo, locked myself in, got on the loo only to start coughing, and then promptly threw up while on the loo. The sick landed in my knickers and all over the floor. I binned my knickers, cleaned up the toilet room, and spent the next few hours wearing no knickers as that day I'd forgotten to pack spares in my handbag and couldn't get out anywhere to buy more - and certainly wasn't going to send the office junior out to buy me knickers!
I felt quite humiliated with myself and now feel like I brought it on myself because I've not diligently done my pelvic floor exercises for the last three years since birth of my first child. I did do them in the months after the birth, and sporadically since, but definitely not 10 a day for the rest of my life or whatever they tell you to do. Is it my fault? Or is doing a bit of wee when you have a bad cough and are nearly 7 months pregnant with second baby normal? No answers in the negative please 
So glad it's almost the weekend and I can sleep. If the sciatica lets me get comfortable...
