I am virgin, had no child but when i drink something a few minutes later i really have to pee and even if i try to hold it i cant. especially when its cold i need to pee urgently. i use some antidepressants can it be the reason? no urinary infection?

Cystitis?: These symptoms suggest possible overactive bladder, or perhaps non-infectious inflammation of the bladder, such as interstitial cystitis. Some antidepressants can cause interstitial cystitis. You'll need to see a doctor for professional evaluation. If you're seeing a GP or some gynecologists, or if you're uncertain of your doctor's expertise in this area, ask for referral to a urologist. Good luck
