Thanks for the query.
A chemical pregnancy is one where the pregnancy result is positive or mildly positive, but there is no evidence of a sac anywhere on ultrasound to call it a pregnancy. On repeating the test after 48 hours, we expect the value of hCG to rise, in such a case we have a hope of a pregnancy, if the levels fall, it will be a chemical pregnancy and no further progress. The value of 10.5 is perhaps too low to call it a pregnancy right now.
Hope this helped.
