Hi. Once In A Month I Had A Day When

Hi. Once in a month I had a day when my urine is irregular. I feel I need to go to washroom urgently but when I visit washroom there are only few drops. Plus k feel some kind of cramp in my bladder also. During this day my urine smells like a sweet coconut. After such a day or two I be perfectly fine and urine is also normal. Is this an issue to be considered or is it normal.?
