Too much fluid

At my precious regular appointment, I had my glucose test which was 99. The doctor was I was right in the middle and passed wonderfully. However, at my growth ultrasound baby is measuring on the larger side and I have too much fluid. They did some more labs and a urine analysis, which all came back normal. Has anyone had any experience with this? I have to go back in a week for a repeat ultrasound and an appointment with a high risk doctor. My last pregnancy I had too much fluid towards the end but that was it. I was induced because of it at 39 weeks and had no complications. I don't know what is causing this and/or is it serious because it's starting so early? Looking for any insight to ease my mind 😊
