Hcg levels

Melissa • I`m a newlywed who just got married August 23, 2014. My hubby and I have officially been together for 4 years and are trying for our rainbow baby. We lost our first at 8 weeks in December. <3
Had my 2nd blood test this morning to see if my levels doubled. They started at 55 on monday. Hoping this is a good sign!
