Same here, the nurse called and told me I have UTI so I'm on medication for a week. Plus yeast infection cream. I heard it's common and it's ok as long as It get treated. Just make sure you drink plenty of water, some cranberry juice will help too.
It is probably a bladder infection, that your doctor caught early. It is a good thing they caught it now before you started feeling any pain or discomfort. you will probably be given a medication to clear it up, drink plenty of water and you will be fine.
I'm 10w1d and just found out I have bacteria in my urine too. My dr said it's very common and nothing to worry about. They gave me medicine to take twice a day for a week. Hope that eases your fears some.
