Urine colors

So ladies lately I've noticed my urine has been changing colors often and I'm getting worried. Sometimes it's cloudy and sometimes it's yellow (like it's supposed to be) but today I peed in my little cup (I was taking a pregnancy test bc we're currently trying) and it was clear.. My pee has never been clear like water before and it's got me worried bc I don't drink enough water to make it clear like that. I also know my urine shouldn't be cloudy either like it has been. I am calling my doctor to make an appointment but does anyone know what could be going on? I'm afraid something is wrong with my kidneys. I am not having any symptoms of a uti or kidney infection. I used to get uti's often though..
