Welcome to Healthcare-Magic
Greetings of the day
It could be just a normal variation of variation in the periods.
Its absolutely normal
If you have other urinary complaints like urgency, increased frequency, burning while urination, would suggest you to get an Urine Microscopic examination done to rule out Urinary tract infection
In case you need any further assistance, will be glad to assist you.
Wishing you happy and healthy life
