Frequent urination?

Hey guys so this is kinda tmi but I'm peeing a lot more often than usual and feel like I have to even when I don't. It doesn't sting or burn and my vagina is normal, not itchy or sore it's just this. Any ideas of what it could be? I've had unprotected sex with my bf multiple times but took a test that came out negative so I'm really unsure. 😕
If anyone has any ideas that could help greatly, thanks.🙂
