Protected sex...

I have been having protected sex for some time, me and my significant have both been tested and are clean from STD’s. We had protected sex yesterday and today I feel like I have the symptoms of a UTI (feeling of frequent urination, specifically) and there is an odd smell coming from my vagina. I have had the issue of the UTI symptoms before- any tips to help that situation would be amazing, but I’m not sure why there is an odd smell, any thoughts??
