just back from A&E and being catheterised after not being able to pee for 5 hours. Am 11.5 weeks pg and never had this problem in my life before. Initial test for urine infection was clear. Made mistake of googling and see that it's described as being very unusual - which threw me a bit, as figured it was probably just a common pregnancy problem. Got my 12 week scan on Tues and been advised by A&E doc to tell my own hospital about today's problem. Still not sure I'm going to be able to pee now, sorry to give so much info, but trying to get a sense of perspective. Have bought large bar of Green and Blacks in case heading off to A&E again shortly
