Your Baby: Forming New Features
It's been four weeks since you conceived, and the embryo is now six weeks old. (Remember, the age of a fetus is calculated from the beginning of the last menstrual period - not from the actual date of conception, which usually happens two weeks later.) Still less than 1/5 of an inch long (4 to 5 mm), it has tripled in size and is starting to look somewhat familiar. The brain is developing distinct areas, and the eyes and ears are beginning to take shape. Even at this early date, the heart is starting to pump blood. The backbone, ribs, and muscles of the back and sides will grow out of 40 small blocks of tissue that are developing along the midline!

Your Body: Deciding On A Doctor
Nothing is more crucial to your pregnancy than getting good prenatal care. That means choosing a compatible health-care provider who is a trusted person you can call when you have questions or concerns about you or your baby. In today's world, everything counts: bedside manner, philosophy, type of practice, and medical credentials. For some people, it's the qualifications that count the most.

• The Obstetrician (OB) is an M.D. who has specialized in the field of woman's health and pregnancy. They specialize not only in the care and treatment of the woman during the pregnancy, but also the labor and delivery of the baby.
• The Maternal-Fetal Medicine Specialist, or perinatologist, is an OB who has received special training to care for high-risk pregnancies. Women may choose this specialist if they have had a previous complicated pregnancy, have a multiple birth pregnancy, or have preexisting medical conditions.
• The Family Physician (FP) according to the American Academy of Family Physicians is an M.D. that has chosen to study family practice medicine. This encompasses treating people of every sex and age with a diverse knowledgebase of all diseases as well as taking care of women who are pregnant. While the family physician delivers some babies, some women may be referred to a specialist for their pregnancy.
• The Certified Nurse-Midwife (CNM) is a person who is educated in nursing and midwifery (receiving the proper credentials and certifications in both areas). A nurse midwife is focused on caring for women who are pregnant and generally is there for labor and delivery as well. Nurse midwives may work within the healthcare community, hand in hand with hospitals and physicians, in caring for you during your pregnancy.

Each type of medical practitioner will treat you and your pregnancy differently. So before you decide on "the one," research each practitioner and practice as extensively as you can.

Weekly Tip
The telltale sign of pregnancy -- morning sickness -- may set in this week. To ease your queasy tummy, try keeping it full at all times. Eat small meals every two to three hours, drink lots of water, and never leave home without a healthy snack in your bag. Some mothers' favorite snacks include power bars, graham crackers, plain crackers, and dried fruits and nuts. Even if you do end up vomiting, at least you won't end up dehydrated.
