Sorry if this is a stupid question but I am 19 weeks pregnant and think I might have a bladder infection. I need to wee All.The.Time. I can see 3 times in 10 minutes and am lucky if I can go an hour without. The baby feels very low so thought it was just sat on my bladder but I am starting to think it might be an infection! Doesn't hurt when I wee but does after sex. I thought this might be thrush but got a pessary from doctor and used 4 days ago but doesn't seem any better. This is my 3rd pregnancy and never had such bad problem until right at the end with my 2nd.
