Anatomy scan

Had the anatomy scan today at 21 weeks. We already knew she was a girl (I was still nervous theyd say it was a boy). And saw all her little organs. Found out I have an anterior placenta today and babys head was down. The tech was all in my pelvic region and it kind of hurt. Her little feet were up a little above my belly button. She was measuring a bit behind 20w4d but not enough to change due date. She weighs about 13oz so a little under a pound but tech she said looks good as ever
