Low bhcg level

Joanie
I'm really worried. Can't stop crying.. i had cramps and less pregnancy symptoms the past 3 days so i went to the ER. My bhcg levels are only 550 and i'm 5 weeks 5 days. The doctor said it was low and it might be a miscarriage. I have to repeat the blood test monday. I love my little bean already. I'm so scared... :'(
