So I had my blood drawn on Saturday. My HCG was only 31. I had low hcg with my son as well, and knew I was early in my pregnancy, so they had me go in Monday for a draw. They just called me and said my hcg was only 42. He said that's abnormal but I have to repeat my blood test Thursday or Friday. Could be fine, but  I couldn't even focus on what my dr said after he mentioned possible miscarriage or ectopic pregnancy. Has anyone had slow rising hcg levels and still had a viable pregnancy?
