An inversion would most likely be a signal that a recession is imminent. An inverted yield curve has a perfect track record of predicting recessions, according to RBC's Jonathan Golub. You can see this in the chart below â the shaded areas are recessions. Business Insider
As pregnancy tests, quantitative blood tests and the most sensitive urine tests usually detect hCG between 6 and 12 days after ovulation. However, it must be taken into account that total hCG levels may vary in a very wide range within the first 4 weeks of gestation, leading to false results during this period.
And your body starts producing hCG only after a fertilized egg implants in the uterus. If it's very early in your pregnancy, your body might not have produced enough hCG yet. In that case, you'd get a negative result at first. Also, some tests are more sensitive than others, and no test is 100 percent accurate. And a few women have such low levels of hCG during pregnancy that home tests can't measure it.
