Hello! , today i went in for an ultrasound again....doctor said" you are at 5 weeks exactly" i tried to read the number on the screen and its aid....4 and hten 11.74mm and if the gestational sac is REALLY 11.74mm then how on earch is it 5 weeks??? we did not see a yolk sac or fetal pole and he said thats really normal since its early. Come back next week . I am just wondering why i was not diagnosed with m/c since i have been reading that the discriminatory level for seeing a yolk sac is 8 mm......i am so confused. ANyone with a simmilar experience?
