What is the normal blood sugar range in the morning? A normal blood sugar range in the morning, also known as fasting blood glucose level, is between 70 milligrams per deciliter and 99 milligrams per deciliter, according to the Virginia Mason Medical Center.
In these early weeks of pregnancy the embryo is attached to a tiny yolk sac which provides nourishment. A few weeks later, the placenta will be fully formed and will take over the transfer of nutrients to the embryo.
Also, as the placenta itself grows, it's likely to grow toward the richer blood supply in the upper part of the uterus.) If placenta previa is seen on your second-trimester ultrasound, you'll have a follow-up ultrasound early in your third trimester to recheck the location of your placenta.
