Procedures
You may be scheduled for additional ultrasounds, though. Your doctor will want to keep a close eye on the position of the placenta as well as on your baby's growth. A low-lying placenta has the ability to harm the baby but that's usually in severe cases, with additional circumstances.
Self-care
Usually something like the placenta sitting too low can be a worry for placentia-previa. But if your doctor told you not to worry, he probably meant that there isn't anything to worry about yet and he was just making sure with a careful ultrasound that everything is okay. If they are being so careful, you will know if a problem is brewing.
