I hope it means you're about to get some good news!!! The reason I found out I was pg with DD1 was when I woke up at 4am one day with a raging UTI and had to go to the hospital to get a doctor's certificate because I was due at work at 6am and knew I couldn't go in the state I was in. The nurse did a routine pg test and told DH and I we were expecting! We had been trying but I continued getting AF (although lighter than usual) so I was nearly 8 weeks along without having a clue!

Then when we started TTC the second time, I got a UTI and that 'funny' taste in my mouth, and sure enough, a POAS the day before AF was due confirmed it. So in my experience, yes, a UTI could well be a symptom that you're about to be a mum!! Good luck, I really hope you are UTD, although having a UTI is a cruel way to 'celebrate' it!
