Pregnancy Week 6

Age of fetus 4weeks.
How Big Is Your Baby ?
The crown-to-rump length of your growing baby is 0.08 to 0.16 inch (2 to 4mm). Crown-to-rump is the sitting height or distance from the top of the baby's head to its rump or buttocks. This measurement is used more often than crown-to-heel length because the baby's legs are usually bent, making that determination difficult.
Occasionally, with the proper equipment, a heartbeat can be seen on ultrasound by the 6th week. Ultrasound is discussed in detail in Week 11.

How Big Are You?
You may have gained a few pounds by now. If you have been nauseated and not eating well, you may have lost weight. You have been pregnant for 1 month, which is enough time to notice some changes in your body. If this is your first pregnancy, your abdomen may not have changed much. Or you may notice your clothes are getting a little tighter around the waist. You may be gaining weight in your legs or other places, such as your breasts.

If you have a pelvic exam, your healthcare provider can usually feel your uterus and note some change in its size.
