Pinkali37, a nn pg UTI, ime, was usually a stinging upon wee-ing and needing to go very often. When you're pg this changes apparently, and I just had pain low down in my abdomen which, if I recall correctly, was coming in waves. There was no bleeding.
I was heading home for lunch on a Friday iirc, only had 30 minutes lunch break, thought this is not right, turned around and went to gp clinic. The receptionist said they were all in a staff meeting, could I come back? No way, I'm staying till I see someone!!
A kind gp came out and saw me, palpated abdomen, took details and a sample and explained that it was likely to be a mild UTI, I said how come, the symptoms are not UTI.... He said that symptoms can be very different during pg. (Incidently sample did not confirm UTI but I drunk more liquids and cranberry juice so I think I just flushed myself out).
I was very scared, and then had to explain where I'd been to work...
But as others posted, although you might just have normal pg uti, it may also be more serious so trust instincts and get checked out for peace of mind. Do not ever think that you're being a nuisance and wait it out, if you are at all worried get seen to and camp on their doorstep if you need to, they will see you.
I'm keeping my fingers crossed that all of you who are worried atm are merely suffering from uti
