If there is a hormonal stimulus to the endometrium, one should expect regular withdrawals with progestagens in adequate doses. With no withdrawal bleeds and a thin endometrium on us, stop therapy and wait. With no withdrawal bleeds and a thick endometrium perform a D&C.

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.
