The wall of the blastocyst is one cell thick except in one area, where it's three to four cells thick. The inner cells in the thickened area develop into the embryo, and the outer cells burrow into the lining of the uterus and develop into the placenta. The placenta produces several hormones that help maintain the pregnancy, including human Chorionic Gonadotropin hCG , which prevents the ovaries from releasing eggs and stimulates the ovaries to produce estrogen and progesterone continuously.

Home pregnancy tests measure levels of hCG in your urine. The placenta is fully formed by 18 to 20 weeks but continues to grow throughout pregnancy. At delivery, it weighs about 1 pound. The placenta connects to the umbilical cord through thousands of microscopic "fingers" of tissue chorionic villi containing a network of blood vessels. The villi are formed by 6 weeks of pregnancy, and your blood fills the spaces around them by 12 weeks.

When your blood comes in contact with the villi, nutrients are exchanged for waste through the villi walls. The villi also act as a filter, preventing some viruses and bacteria from reaching your baby, while allowing molecules of everything you ingest as well as antibodies and gases to pass through.

Along with all the good things that are transferred to your baby, some harmful ones can cross the placenta too. These include alcohol, nicotine, and illegal drugs as well as some medications. No safe level has been established for alcohol consumption during pregnancy , and experts recommend not drinking any amount while you're expecting. The same goes for smoking and using illegal drugs.

Although marijuana is legal in some states, experts recommend against using it during pregnancy. Discuss any supplements or over-the-counter or prescription drugs you may need or want to take with your healthcare provider.

A few minutes after your baby is born, the placenta detaches from the wall of your uterus and is delivered through your vagina.

You'll have a few contractions, but this stage of childbirth usually lasts only about five to 10 minutes and feels more like menstrual cramps than labor pains. If you're having a c-section, your doctor will remove the placenta manually. If you want, and if you've made prior arrangements with your provider, you can save the placenta. Some women believe that encapsulating and eating the placenta after birth helps them recover faster, though there's no scientific evidence to support this claim.

Also note that there are potential risks associated with consuming the placenta, including infection and heavy metal contamination. Be sure to discuss this topic with your provider if it's something you're considering. If you experience spotting or cramping, your doctor or midwife can check your body and baby, as well as make sure the placenta is developing properly.

Sometimes, your doctor or midwife will recommend bed rest, hospitalization or a change in birth plans.
