See answer: Your urinary symptoms are consistent with a UTI and if so, should resolve within 3-5 days of taking the appropriate antibiotic. If symptoms persist, i would recommend both a urinalysis and culture to verify the diagnosis and direct treatment. If your weight gain has occurred over a short time frame and there has been no marked increase on your dietary intake, then likely due to fluid retention.
