Constantly having to pee!!

Alyssa
I am 12 weeks tomorrow and I cannot stop running to the bathroom today!!! I feel like I constantly have to pee!
I don't have any symptoms of a UTI, or infection. But it's all of a sudden now! I didn't have this problem before!
I have been noticing some uterine twinges today..... could it just be that I am expanding?
Anyone have any advice or can relate?
