Excessive Weeing

Grace
Hi Everyone :)
I'm 23 weeks and 4 days and for the last 2 days I've been weeing excessively without drinking much at all. I know it's important to keep hydrated but I'm so sick of going to the loo, I've lay off drinking much at all. I am constantly bursting for a wee, and when I go, it's like a river! Where is it coming from???
I know during pregnancy you have to go a lot more but the increase over the last 2 days is drastic!! 
I'm also feeling huge and massively bloated. 
This is my 2nd pregnancy and I can only compare it to the feeling I had the hour leading up to my waters breaking and labour starting with my 1st baby.
Is this normal?
