What Are My Chances Of Miscarriage At This Time?

Hey there, a month ago I had a miscarriage, and now I am pregnant again. I was estimated to be about 6 weeks with my miscarriage, yet my HCG level never got higher than 62. What is the chances of this repeating itself? Also, being my levels were so low, is it likely it was just a chromosomal problem that happened during implantation?
