They did a transvaginal ultrasound on me, and only located a gestational sac , but no yolk sac. My HCG levels checked to be 11,000 which is high, but there’s no yolk sac? Checked my tubes for possible ectopic pregnancy and found nothing. Any similar cases? What do you guys think? Does it sound abnormal ?
