Frequent urination from 1 month

It started 1 month before. It started when I outside accidentally stopped urinating in middle for 10 min. When I reached home I went to bathroom since from then I am urinating frequently. I went to Urologist bt every test came negative.

I am just 19 years old

Bt I not explained them how it's started

Please help me it's ruining my days

I was doing this at night - nocturnia.  It was normal for me, since my bladder produced over 2 liters in 8 hours.

I have since stopped drinking too much liquid.  My problem was triggered by drinking too much liquid at once, and now am in a Catch-22 (bad) situation.
