is my uti gone?

Hey guys! A week ago I had my period but had my first UTI 2 days in, and my period ended. After my UTI, I got discharge similar to when I finish my period so I thought it's just finishing off whatevers left. I'm currently finishing off my UTI medicine, but I'm noticing a fishy smell, and a small amount of darkish grey discharge. I'm no longer experiencing any symptoms of a UTI, (pain when I pee, excessive urge to pee), but the smell and discharge is making me wonder if it's really gone (it only lasted 2 days)? Or is this some other type of infection and should see the doctor? or am I just going crazy and this is normal?

ps. haven't had sex in a good 2 weeks because of my period.

early thanks to any response ❤
