Every pregnancy has a yolk sac otherwise there wouldnt even be a "sac" there. (my ob told me this after i suffered my second mc) There probably wasnt a fetal pole..yet. Its still early. Your hcg seems normal, and at barely 6 weeks its normal not to see a heart beat yet. Good Luck
Hopefully its just to early. I was around 5-6wks and they didn't see anything on ultrasound either and I was having major bleeding and was told to prepare for the worst. And she is now a healthy 10month old. Good luck
i know exactly what your going through. i found out i was pregnant last night went to the dr this morning for a check up and they said they saw a fetal pole.. im only 4wk1day so they said im either to early or i will m/c again.. ive m/c 5 times already so i know the scary feeling.. i would say if your not bleeding no cramps then it may not be a m/c.. your hcg levels are high, what is your dr saying??
