Why is fetal pole and yolk sac not visible in my pregnancy?
Patient: uterus gravid uterus showing 7 weeks and 2 days sized gestational sac. foetal and yolk sac polex yet not visible in view of an early pragnancy advised re scan after 21 days for gestational viability. inference early pregnancy of about 6 weeks and 5 days means hindi pdf Doctor: Hi,    Thanks for asking . I understand your concern.    Normally gestational sac is evident by 3to 5 weeks of pregnancy. Yolk sac is seen by 5.5 to 6 weeks of pregnancy & fetal pole is evident by > 6 weeks pregnancy.    The inference ( Hindi me matlab  Ki ) of your USG isPregnancy is 6 weeks & 5 days pregnancy ( Hindime.. 6 hapte aur 5 din ka garbha hai).    * Absence of fetal pole at this stage indicates      - Delayed conception,     - blighted ovum ( pregnancy without fetus )        - Ectopic pregnancy with pseudo gestational sac in uterus.    * In this respect I would suggest USG with vaginal probe, as advised after 21 days / to get a second opinion .. to confirm the findings.   Thanks.
