By the way, blood tests for hCG are more accurate than home pregnancy tests (especially earlier on), and a quantitative hCG test specifically measures the amount of the hormone you’re producing. In blood tests, hCG levels are significantly higher (30 to 50 percent) in twins and multiples, but again, it takes a few days for the difference to appear.
