I am 26 Years old and 21 weeks pregnant this week I had a Level 2 Ultrasound because at my other ultrasound the tech had a hard time getting certain pictures of the heart and Spine, The specialist I went to to have this done told me that everything looks ok except for that there is dilation of both kidneys showing on the ultrasound one measured at 5mm and one at 6, he also told me that 95% of the time that this would go away by delivery, and that it is more common in Boys, and that is what is is, but I am still a nervous wreck I worry about everything since my misscarriage last year, my AFP test came out excellent and also all of my routine visits have gone very well so far, but then I also worry that I don't feel the baby move alot and at the last 2 ultrasound he was laying on his back, is that normal, I hear alot of people say the baby is constantly changing positions? Does or did anyone have any of these things or know someone who did?
