Removing IUD, peeing like crazy

Is my body getting rid of fluid retention? I’m not drinking more water than usual but I am peeing large amounts almost hourly and lost a small amount of weight since removing it the day before! I’d say something wrong with my bladder if I felt like I needed to pee very often without much coming out, but a lot of water is coming out each time. I am off hormonal birth control for the first time in ten years.
