When talking about the size of a developing baby, most healthcare providers will discuss the size in terms of `crown-to-rump` length. Crown-to-rump length simply means the distance from the top of the baby's head to its buttocks. Because the baby's legs are usually bent or tucked inwards, crown-to-heel length is hard to determine. By the sixth week of pregnancy, your developing baby is 2 to 4 mm long. You may have even gained a few pounds at this point. However, if you have been nauseated or not eating well you might have lost weight.

You have actually been pregnant for an entire month now! More than likely, you have noticed some changes within your body and you might also notice that your clothes are fitting slightly tighter around the waist. Some women also gain pregnancy weight in their legs, face and breasts. It is not uncommon to experience heartburn or constipation at this time either. Symptoms are usually not severe at this time. If you were to have a pelvic exam at this point of your pregnancy, your doctor would be able to feel your uterus and would notice some changes in its size. Although you will not be able to hear your baby's heartbeat with a Doppler yet, you might be able to see it beating if you have an ultrasound now.

From week 6 to week 10 of your pregnancy, you will be in the embryonic period. This is a very important time of development for your baby and the embryo is most susceptible to experience developmental interferences at this time. Although the embryo is still very small, it is growing and developing rapidly. Your baby's early brain chambers are forming and the eyes are also beginning to form. Buds will appear and will develop into arms and legs in later weeks.

Many pregnant women will have their first prenatal appointment around this time. Generally, the first appointment is the longest and your doctor will gather a health history of you, the father and your families. You should ask questions and get to know your healthcare provider well. Your doctor will probably ask about any prior medical problems, your pregnancy and birth history and other gynecological concerns. You should tell your caregiver about any prior miscarriages, stillbirths or abortions that you have had. You should also tell your doctor about any medications that you take or allergies that you have. Your doctor will give you a pelvic exam and a Pap smear. During a pelvic exam, your doctor will be able to determine if your uterus is the appropriate size. A breast exam will also be performed. Lab tests may also be done at this prenatal visit. Some doctors will also perform early ultrasounds during the first prenatal appointment to date the pregnancy, confirm the pregnancy or check for abnormalities.
