frequent urination??

Hailee
I'm up so late tonight getting my apartment all squared away and I realized that I've been peeing a lot. It doesn't burn. It doesn't itch. There's no pressure or weird feeling. Nothing less than just having to pee. I haven't drank anymore fluids than normal and I feel "heavy" so to speak. I just peed like 20 min ago, and I swear it feels like I have to go. I've heard this is an early sign of pregnancy, but I don't want to get my hopes up. I tested tonight at 12dpo & it was negative... my expected AF is Monday 1/23. Any thoughts??
