Hi. I Was Sent To Hospital As I Was Leaking

Hi. I was sent to hospital as I was leaking water. Checked everything and seemed fine. Was sent for an ultra scan and was told the stomach was enlarged. I'm measuring 97 percenti. Also had to get second onion on an issue with kidney values. Hospital Didnt explain things and said everything was fine, and sent home. Have midwife Friday but very worried. Do you know what this means?
