Radiology notes that one benefit of the procedure is that a woman need not fill her bladder with water—an uncomfortable prerequisite for an abdominal ultrasound in early pregnancy—prior to a transvaginal procedure.The ultrasound probe, once inserted, allows the ultrasonagrapher to visualize the uterus and ovaries through the cervix, which forms the barrier between vagina and uterus.

In this case a follow up scan after an interval when normal growth can be expected to now show these things will be recommended.

The first part of a pregnancy to be visible on ultrasound is the “gestational sac” which can be seen with a transvaginal scan approximately 3 weeks after a baby is conceived. During the next 2 weeks first a “yolk sac” and then a small “fetal pole” become visible.

When the fetal pole grows to more than 4mm the baby’s heart beat can be picked up on the ultrasound and these things normally occur 4 ½ weeks after conception (about 6 ½ weeks from the last menstrual period).

While ultrasounds have not been found to cause damage to either mother or baby, they're nevertheless not done unless medically indicated.

For this reason, practitioners differ with regard to their approach to ultrasounds, and some don't rely upon them heavily.

Pro notes that transvaginal ultrasounds have the advantage of allowing visualization of an embryo much sooner than abdominal ultrasounds—typically embryos of only four to five weeks of gestational age will show up on a transvaginal ultrasound, while it takes nearly six weeks for abdominal ultrasound visualization.

A transvaginal ultrasound, unlike a traditional abdominal ultrasound, requires the insertion of a probe into the vagina.Ultrasounds help physicians assess the viability of a pregnancy with regard to placement of the embryo, gestational age, and visible signs of appropriate development.While abdominal ultrasounds are common in later pregnancy, transvaginal ultrasounds allow for earlier imaging of an embryo, and many practitioners prefer them for early visualization.The purpose of ultrasonagraphy during pregnancy is to ensure normal progression of the pregnancy.American explains that early ultrasounds help physicians confirm that a pregnancy is viable.If a full diagnostic ultrasound would be more appropriate for your situation, because you’re further along in your pregnancy or experiencing medical problems, our staff will be happy to refer you to an OB-GYN who can assist.
