Your Baby’s Development
Until now, the embryo has been a mass of cells, but by this point in your pregnancy a distinct shape begins to form. The neural tube, which will eventually form into the spinal cord and brain, runs from the top to the bottom of the embryo. A bulge in the center of the embryo will develop into your baby’s heart. At this time, the placenta develops. It is through the placenta and its fingerlike projections, called chorionic villi, that an embryo receives nourishment from its mother.
Even if nausea hasn’t hit you yet, you’ll want to steer clear of certain foods when you’re pregnant. Foodborne illnesses, such as listeriosis and toxoplasmosis, may cause birth defects or even miscarriage. Here are some foods you’ll want to avoid:
- soft, unpasteurized cheeses (often advertised as “fresh”) such as feta, goat, Brie, Camembert, and blue cheese
- unpasteurized milk, juices, and apple cider
- raw eggs or foods containing raw eggs, including mousse and tiramisu
- raw or undercooked meats, fish, or shellfish
- processed meats such as hot dogs and deli meats (these should be well-cooked)
- fish that are high in mercury, including shark, swordfish, king mackeral, or tilefish
Toxoplasmosis can also be spread from soiled cat litter boxes, so try to have someone else clean the litter box during your pregnancy.
