Light Cramping? Possible Miscarriage?

Woulfe

Yesterday I had some very light cramping and have just found out I was pregnant a few days ago... I miscalculated how far along I would be and gave the wrong dates to where we all thought I was 4 weeks going on 5 but I'm really only 3 weeks. They said my HCG was only at 110. The cramping had gone away hours earlier but they said they only saw a prolapsed uterus but no sack. Quickly the docotr came in attempting to rush us out like they had been the entire time and simply put that he was 95% sure I had miscarried however there was none of the signs especially not blood or tissue or any discharge at all aside from the really light cramping that only got worse with physical labor and stress. Could he be wrong? I'm getting another opinion today but he has crushed my hopes...
