Poor Shelby! Frequent urination and straining is certainly not normal, and I agree with your concern - a UTI seems possible, as well as crystals in the urine or bladder stones. Even though she seems fine today, I would still take her to the vet for an exam and urinalysis to assure that everything looks okay. Better to catch and start treating a UTI sooner rather than later! I hope that all goes well!

I am sorry to hear this. It can take 48-72 hrs for antibiotics to reduce the bacteria load enough to improve clinical symptoms.
However the straining is concerning to some degree because pets can strain from either cystitis (inflamed bladder) or from a urinary bladder stone blockage. With Chichi carefully for signs of a true urinary blockage, which would involve a lack of any urine output, a swollen abdomen, and discomfort. If you have any question whether she could be blocked or not, then it is best to have her evaluated by your veterinarian, or anyone that is open today, immediately!
However if she is still able to urinate small amounts and going frequently (more than once an hour) then there are more likely signs of cystitis (inflamed bladder), which should improve within the time frame mentioned earlier, and should resolve completely after 7-10 days if this is an uncomplicated UTI.
