Hi Confused - this happened to me too with my 2nd MC. For me the end result was a blighted ovum - which is a time of MC, where the baby doesn't develop, eventually the levels stopped rising at the correct rate although still rising, but unfortunatley it was not a posative outcome for me.
FX that your outcome is different.
Not sure where you are in the country but if you are by chance in the waikato the epac nurse is awesome, hang in there hunxxx
