<p>I needed to pee pretty badly in the morning but decided to hold it in. The feeling went away for a couple of periods, and I even drank more water. During my last two periods of the day, I could feel my bladder ready to rip apart and burst. But I held it in. During my very last period, the urine was slowly being forced down my urethra, so I did that sucking/suction feeling (you know, the action that you do to stop that flow of urine, just to see if you have the willpower). I felt mild pains, as if I were pumping air into my bladder. My vision blacked out for a fraction of a second, twice. Then I went to the bathroom.</p>
