scared

:( I am scared that I am going to lose this baby, My HCG levels are going up but not doubling. My first blood work was 18.8 my second was 31.1 and my one from yesterday was only 54 there was a week in between the second and third. I'm really scared I don't want to say goodbye to another baby. Anyone have any advice or good vibes they can send to me. Thank you. :(
