Good day, pregnancy is 5 weeks and 2 days, at 4.6 weeks ultrasound showed a fetal yolk 4mm, yellow body 23mm with good blood flow. hCG level 1.02 - 57 mIU, 7.02 - 714 mIU, they scared me on ultrasound said too small fetal egg for our term((( Can someone decipher it, suggest... even trying to stand now is not worth it.. all the same won't be put in account.
