3 weeks.
The placenta attaches to the uterus 4-5 days after conception (the sperm and egg meeting). It is fully functional by 12 weeks.
At 5 weeks of gestation, the embryo is still in the early stages of development, and while the placenta is not fully formed, the initial structures that will develop into the placenta are starting to form. The placenta begins to develop from the trophoblast layer of the embryo and will continue to grow and mature throughout the first trimester. By this time, the placenta is providing some early nutritional support and facilitating gas exchange, although it is not yet fully functional.
yes
Mod Podge typically takes about 2-3 weeks to fully cure and become completely dry.
At about 3 weeks, they will be fully weaned/independent.
You may get a negative test as what is being tested is the hormone produced to maintain the pregnancy until the placenta is fully formed. The placenta is formed by about 13 weeks and HCG gradually reduces. some may still be detectable but a negative test does not mean you are not pregnant.
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.
trophoblasts/chorionic villi and the uterus form the placenta
The first time you get your shot it usually takes about two weeks, to become fully effective.
After a miscarriage at 12 weeks, the placenta typically does not pulsate. Once the pregnancy ends and the fetus is no longer viable, the placental blood flow ceases, and the placenta will gradually begin to separate and be expelled from the body. Any residual pulsation might be due to blood flow in the mother's body, but the placenta itself would not exhibit pulsation similar to that during a viable pregnancy.
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.
