Hello, I have a frequency of urination. I haven?t seen a doctor yet. I don't have any medical condition. But 2 months ago I had tonsil infection and fever. I am 18 years old. Unmarried. Yes, I don't want to wake up at night and go to the bathroom. That's why I hold my urine at all night. But also I feel like there is always some urine left in my bladder after urinating. I drink a lot of water. I always feel thirsty. My period is also untimely. But it starts after 25-35 days. Sometimes in the rare case around 40 days. What to do? Thank you.
