The gestational sac and placenta will grow, but the gestational sac containing the embryo remains empty. It causes a miscarriage in the first trimester of pregnancy.fetal pole may be identifiable on endovaginal ultrasound (1-2 mm) fetal heart rate ( FHR) should be ~100-115 bpm. gestational sac should be ~10 mm in diameter. 6.5 weeks. crown rump length ( CRL) should be ~5 mm. 7-8 weeks. CRL is between 11-16 mm. cephalad and caudal poles can be identified. 8-9 weeks.
