single live intra uterine gestation of 20 weeks 1 day A.C 147mm EFW 327 g placenta: Grade II Placenta placed posteriorly
A posterior placenta grade 2 means that the placenta is located closer to the back. This is commonly seen at 30 weeks of pregnancy and is considered normal.
The placenta attaches to the uterus 4-5 days after conception (the sperm and egg meeting). It is fully functional by 12 weeks.
trophoblasts/chorionic villi and the uterus form the placenta
yes they can go to 41 weeks and very rarely to 42 weeks but after 41 weeks there can be a danger to the baby as the placenta starts to stop working efficiently.
From what both my doctors have told me the placenta is producing its own progesterone by week 12. I just stopped taking crinone and Im nervous Im 12 weeks 4 days pregnant.

During this period your uterus is stretched to the max. You can feel your body change to fit the baby. Your placenta is at a mature point during the pregnancy.
Actually, the bleeding behind the placenta at 7 weeks gestation is called a "subchorionic" hematoma. This happens sometimes in pregnancies when the fetus attaches to the uterus. This is not necessarily a primary indication of a placental abruption and most pregnancies with subchorionic bleeds resolve after a few weeks
20 weeks ago.
THE PLACENTA is visibly formed at 12 weeks gestation. At about this point, the placenta takes over a very BIG job from moms hormones. The placenta is now 100 percent responsible for nourishing the fetus. The placenta attaches to the baby at the umbilical cord, or the "belly- button." The placenta is called the babys life support system because it provides everything the fetus needs to stay alive until birth. Without the placenta, the baby would die.
