The general recommendations are to wait two weeks if we only see a gestational sac and at least 11 days if a gestational and yolk sac are seen without a fetal pole. And repeating an ultrasound still wonвЂ™t be able to reassure the patient that the fetus is alive and growing, if we do it too soon. But it takes time to move through the early stages of pregnancy. Newly pregnant women get anxious if we donвЂ™t see both a fetus and a heartbeat on the first ultrasound and frequently want to come back soon after for another look. If the first ultrasound doesnвЂ™t show a developing baby with a heartbeat, when should the next one be scheduled? ItвЂ™s important that this ultrasound is performed vaginally for high-quality pictures. Just like pregnancy tests, if thereвЂ™s variability in the length of the menstrual cycle or when fertilization takes place, then what we see on ultrasound can change. While these are the expected times to see the developing pregnancy with an ultrasound, not all pregnancies develop along the same timeline. Stage Four: Approximately six weeks after a pregnant womanвЂ™s last period, we can see a small fetal pole, one of the first stages of growth for an embryo, which develops alongside the yolk sac.The ultrasound typically shows a gestational sac and within it we can see a 3-5 mm bubble-like structure, which is the yolk sac. Stage Three: This is usually about five and a half weeks after a pregnant womanвЂ™s last period.The ultrasound commonly shows a small collection of fluid within the lining of the uterus that represents the early development of the gestational sac. Stage Two: This is usually at four to five weeks after a pregnant womanвЂ™s last period.Stage One: If performed around the time a womenвЂ™s menstrual period is expected, this ultrasound typically shows a fluffy, thick lining of the uterus thatвЂ™s preparing for the fertilized egg to implant.The ultrasounds we might do prior to that, and the information those exams would reveal, generally occur in four stages: 4 stages of early pregnancy and what we might see on ultrasoundДЄn ultrasound is a routine part of prenatal care at six to nine weeks.
