Sonography in early pregnancy failure.
Early pregnancy can be best divided into embryonic and fetal periods (dividing line 70 days after last menstrual period), which more naturally reflect developmental changes, morphologic appearance, loss rates, and concerns about teratogens. Newer endovaginal probes and a better understanding of anatomic landmarks and expected growth rates can improve clinical management and patient counseling.
