I dont know whats wrong with me :S?

bit embarrassing but its really weird after I drink anything I immediately, desperately have to pee. all I've been drinking is water and a mug of peppermint tea. last night I woke up about 6 times to pee when I usually wouldn't wake up once. the day before I had really bad stomach pains in the morning but I didn't want to miss work so I went out and after about an hour they went away, I dunno if maybe its connected to this. does anyone know what this is??
