I'd call your Dr about a UTI. I had one recently (at 29 weeks) and my only signs were more frequent need to pee and not much coming out. I've had heaps of past UTI's so i was surprised that i had one as i had no pain or stinging this time around. The hospital took it very seriously and were even going to admit me for a week on IV antibiotics cause apparently a UTI in preg can bring on premature labour. I ended up convincing them to let me take oral AB's at home and a week later i was tested and clear

Hope you're in the clear but it's better to play it safe and get your urine tested! Good luck.
