Have to pee!!

I am 8 dpo. 8 days to go til AF. YESTERDAY I started having to pee allll the time. Today not any better. I thought at first UTI but now the more I think about it and realize I have NO other symptoms either I started thinking...whoa! I am not prone to utis at all. Only ever had one in my whole life. And nevvver have to pee this much! Thoughts????
