There isn't sufficient information to give a specific diagnosis. I would advise you to visit a gynecologist so that you can be examined and undergo investigations such as urine routine, ultrasound(if indicated by physical examination), etc to find the underlying cause and have it treated accordingly. I would advise you to stay hydrated and aim to drink 3 liters of water per day. If the problem persists or worsens visit the ER at the earliest.
