Ultrasound and full bladder


So before I went for my ultrasound 10 weeks 5 days, I drank a lot of water because I had read on here that the pictures came out clearer when you had a full bladder. So my tech asked me if I had to pee and I said yes, and told her why. She said it wasn’t necessary because the baby is already in a sac full of water and she doesn’t know where that idea came from. She also showed me my full bladder 😂 so what do you guys think 🧐 my little sweet potato 🥰
