Hi I'm 19 weeks pregnant and had UTI last month but didn't have any usual symptoms eg burning etc just suddenly was really faint then sick got antibiotics cleared up fine. Yesterday I honestly thought I had gone into labour, again no normal symptoms of burning etc, just suddenly really sharp cramps in my tummy and back, was really scary.Went straight to hospital and again have UTI. Has anyone else had experience of UTI's and is there anything I can do to stop them/catch it before the pain is so intense? I drink loads anyway, I'm very clean,sex is out of the question at the mo so what else can I do if anything?
