Frequent urination. That i am missing?

I am having frequent urination since 3 days like 10-15 times per day, even today i had it already 14 times and its only 5 pm, i had done my hba1c(5.5)and fbs(84) on 26 may both of which came normal, although i dont have any other classical symptoms of diabetes, so i had my urine routine done, which came back normal but i am still having persistent feel to urinate, the urine often comes normal with no pain(but i have some kind of sensation in urethra after relieving myself very little sensation hard to notice), there is no pain though. as my but since last three days its making me anxious, , can sugar in urine rule out diabetes?or should i get more test done, or is it something else that i am missing? I am scared of this diabetes thing i am just 21 , was having an vey unhealthy lifestyle but since last i get tested(hba1c and fbs) i have completely changed my lifestyle, please tell me should i go for ogtt or hba1c or its normal and i dont have diabetes, i am stressed out, please help 🆘.
