Frequent Urination and spasms?

So I'm sitting at my desk at work, and I think my cell phone is ringing (on vibrate) in my pocket. Turns out it is my body, pelvic area to be specific. No pain, just a rhythmic buzzing feeling. The reason I'm posting it here is because the only other issue which occurred is frequent trips to the bathroom to pee. It's been going on 3 days now. I'm thinking something to do with my bladder and my pelvic floor, possibly muscles or nerves being impinged by my bladder or ? Don't think I have a bladder infection, and all the "plumbing" is working fine except for frequent trips to the bathroom and little output each time. Any thoughts?
