Uti gone?

So yesterday morning after I peed it was abit sore (mild uti feeling) so I started drinking lots of water and had a few vitamin c tablets, now when I go to the toilet it is pretty much normal and I don't have to urge to pee lots... I'm wondering if I've actually gotten rid of it or if I may still have it. I have only had a uti once before and it hurt a lot more than this. I am wanting to avoid going on antibiotics but don't want to stress if I have it or not, anyone know?
