midnight pee

I'm in my week 29 now. And I wake up alMost twice a night just to pee. But when I peed, I noticed that my urine is in either yellow or dark yellow colour. Just wondering whether all mummies to be, do you all drink a glass of water after you peed at night ? Or you just go straight to bed ? Throughout the day, I did drank 3 litres of water so my urine is clear in colour. It's only at night that I don't drink that much.
