By the 6th week of pregnancy, the fetus' heart has started beating and can often be seen early in the 6th week by transvaginal ultrasound. Baby is now about 1/17 of an inch in length and growing rapidly. If an ultrasound were to be performed this early in the pregnancy, baby would look like a round circle in the womb with a small nub on one side. The nub is the attachment point of the egg to the uterine lining. Buds are starting to develop that will later become the arms and legs. Moms pregnant with multiples will see the same progression by week 6.
Week 6 is an exciting time! The fetus has grown rapidly and it's heart has start beating. You can schedule your first ultrasound with your doctor to assess for any risks and to check the fetus’ heart rate.
During the transvaginal ultrasound, you will be able to see the fetus’ heart and hear it beat. This is a special moment for many expectant mothers! A heart rate over 100 beats per minute is a good sign. However, a heart rate below 90 beats per minute can be worrisome and increases the risk of a miscarriage.
Be sure to speak to your doctor about any concerns you may have regarding your fetus’ and your health. Communication is vital to ensuring you have a safe, healthy pregnancy. Continue to relax and maintain a healthy lifestyle as hormonal changes begin to get stronger and fatigue sets in.
