Pregnancy peeing question


I have what is probably a ridiculous question. I know frequent urination can be an early pregnancy sign. My question is whether this is just an increase in frequency of having to visit the toilet or whether it is accompanied with an increase in the amount of pee.

I ask because I feel like I've been in the bathroom all last week (today is 2 days before AF is expected), but there's a lot of pee each time. So I'm not sure if it's just a result of drinking a bit more water or if I should consider taking a test.
