I've been lucky so far, hardly any ms but I'm 32 weeks pg now and twice now (last night and a few weeks ago) I've just thrown up with no warning - feeling a bit ill one minute but no worse than other times (mostly due to acid I think), then suddenly I'm chucking up with barely time to get to a sink. Really worried it will happen at work or on the bus. Also last night I wet myself at the same time - lovely. Really worries me that I can't tell when it's going to happen. Any suggestions??
