So I have done research online. It is a side affect of pregnancy such as the uterus resting on my bladder, just another symptom, or a sign of a uti. It's been going off n on for about a week. It's not every time. At 12+4, could it really be my uterus on the bladder??? Trying a flush for the next 2 days to see if it helps...if not calling in, just wanted opinions.
