Agreed. "missed abortion" and "blighted ovum" are used to the point of meaninglessness.

Did the hCG plateau? Guess I may have missed that. The odds of distant implantation are greater than 100:1, I think.... but, I could happen. In the tube alone is about 97.5%.

I appoligize about the meaningless Subject: line. That is the main problem with digests.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
