Frequent urination;

I’m not sure if I AM pregnant yet, but starting last night I have the sudden urge to urinate. I woke up in the middle of the night to pee, and it’s not like a regular I have to pee it feels like I’ve been holding my pee for a long time. I never wake up to pee in the middle of the night. And I don’t drink that much liquids.. what were some of ur first pregnancy signs? (I don’t have signs of a UTI either)
