You are right, these symptoms could be due to a Urinary Tract Infection. You may wait for a day or two to see whether the symptoms are resolving by itself.
Drink plenty of water. You may also drink 100-150 ml of Cranberry juice ( not diluted, slightly sweetened )daily, which proven to help in UTI.
If the symptoms are not resolving in 2 days, or if there are new symptoms/ existing symptoms are getting worse (like again fever, pain while urination etc) you will to see a Doctor. In that case a Urine routine and culture followed by an antibiotic course will be the best course.
Hope this helps. Thank you.
