Tmi? Is my bladder going crazy?

Ok so for maybe the last 2 and a half weeks every time I sleep I have to pee, like I will wake up more the 3 times a night to pee and I'll stop drinking water like 3 hours before I have to go to bed? Anyone else have this problem? Or could this be a early sign of pregnancy? And like I said it's only started recently and is starting to effect my sleeping habits because I wake up every every couple hours..
