Low hcg levels.

I'm terrified. I'm 3 weeks. Had some light spotting and cramping the day I found out. No more cramping but light spotting since then. It seems to be gone today. Went in for a blood test An my hcg level was 56 ml. She says it's on the low side. The chart they gave me says it should be above 100ml. I know I won't know anything until my next test tomorrow, but I'm confused and so scared of losing this one....

Why do all the online charts list such lower amounts than my doctors chart? If you Google charts it seems like I'm at a normal range. 😭
