Welcome to week 6

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 being formed and 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 fetus' future spine!

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 you can call whenever 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/Gynecologist (OB/GYN) 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) is an M.D. that has chosen to study family practice medicine. Family practice physicians treat men and women of all ages as well as treat children. They also take care of women who are pregnant. Some FP's deliver babies, while others provide prenatal care and have Ob/Gyn or midwifery colleagues who do the delivery.
• The Certified Nurse-Midwife (CNM) is a person who is trained in nursing and midwifery. A nurse midwife is focused on caring for women who are pregnant and generally is there for labor and delivery as well. Nurse midwives generally work with obstetricians as well. Midwives emphasize that birth is a normal, physiologic process, and generally provide a low-intervention approach to 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.
