Help a girl out 😳

Hi ladies, alright so it’s been a little over a week and a half that I notice my pee is very clear and then a few hours later it’s normal pale yellow coloring. I am hydrated but I don’t think I’ve extended that much of my water intake that it’s just clear .... I’m currently 31 weeks pregnant. When I pee even if I haven’t drank much it’s a lot of pee and that’s when I notice it being pretty clear. I mentioned it to my obgyn and she doesn’t seem to be concerned about it, but I am because what if I’m leaking Amniotic fluid. What do you guys suggest ?
