Don’t have to pee?

For some reason I don’t feel the need to pee. It’s been about a week or two since I’ve actually felt the need to pee. I know I have to pee when I get cramps.. it’s like when you hold your pee for a long tome it hurts. That’s the only time I know I have to pee. I drink plenty of water and I don’t drink soda. Does anyone know what’s going on?

I’m supposed to get my period in a couple of days so hopefully that will help.
