"I am suppose to be 9 weeks and 1 day since my lmp (11/22/12) had ultrasound 1/24/13 and said i was only 5 weeks 4 days, my hcg level on Jan. 4th 2013 was 2,637 and on Jan. 24th is was 21,445. Is this ok, or am i going to have a miscarriage?"
Unfortunately this is only something your doctor will be able to answer. Maybe your dates were wrong? Has your doctor suggested a follow up blood test to see if your hcg levels are rising? If not then that might be something to request.
