Hi there took my older sister to ER yesterday due to abdominal pain she was having and spotting. The do doctor said she has a threating MC I'm really worried and the dr. Is also concerns about her HCG level. If the HCG LEVEL THIS HIGH SHOULD WE WORRIE? I really want to be an aunt I was cry, laughing and so damn excited yesterday when we saw the baby heart beat.
