Does anyone feel like the have to pee all the time but don't?

I have been feeling like this for months now (and no I'm not pregnant). Even after I have just gone to pee 30 minutes prior I feel like I have to again but barely any comes out. sometimes it feels like there is constant pressure on my bladder too, especially when I have just eaten a meal. I don't feel like this everyday, but most days I do. Anybody else have this problem? Do you know what it is???
