Happened to my mother in law. Could be your kidney.
I go to the doctor Tuesday. And I'm going to ask. But I don't have burning, or smells. And I stopped All soft drinks. it my first I had a kidney infection and a utiIbut it. Doesn't feel like that.
^ I was at my doctor and they asked about any symptoms of a uti and I told them but they said I didn't have a uti. I don't think that's always the case.
Go to the doctor....sounds like a UTI.
I'm 14 weeks 3 days and its the same for me. I didn't have any problems im having this time when pregnant with my daughter.
