Can a UTI go away on it's own?

I've had cranberry juice, been drinking lots of water.

Three days ago I had the typical symptoms...peeing lots, pain at the end of the pee, and the urge to pee all the time with very light spotting when I wiped. Note! Edit! As soon as I felt a weird pee sensation I immediately started flushing out my body as best as I could. Almost to "make" myself pee trying to flush out all the crap. I didnt wait for the symptoms to get bad.

I was not able to get to a clinic because of work being crazy busy.

And now 3 days later, I'm peeing and there is no pain. No urge to pee all the time. Nothing. Can a uti go away on it's own??
