Yolk Sac

I am 23 days (IVF Transfer) into my pregnancy.
I went for my first ultra sound and it is twins.
Baby A is 12.77mm and a yolk sac is seen.
Baby B is 10.50mm but they could not see a yolk sac.
My HCG level is 16,918.
Is not being able to see a yolk sac normal/Ok in the first u/s or
is baby B not going to develop? Or will it just show up next u/s??

Hello,

A gestational sac and yolk sac need to be seen, but it is very early.  A follow up scan in a few weeks will be helpful.  

Best regards,

Dr. Downing

wow those # sound good.. i had my 1st us and today and found out twins also.. they saw both sacs but sizes are only 9.5 and 9.6mm... beta is at 11000...i hope my numbers are ok.. is this ur first ivf???

I would think if you have baby b, (fetal pole) measuring 10.50mm, then there must be a yolk sac, because that would come before the fetal pole.... maybe they just couldn't see it in the u/s?

This would be my 4th IVF
I also have done 5 IUI.
Twins would mean the world to me
because I would never have to put myself thru
this again.  Many hardships and alot of tears,
and now I'm still holding my breath!
