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.
A positive hCG means that a woman is likely pregnant. The blood level of hcG in a woman with an ectopic pregnancy usually rises at a slower rate than normal. Typically, hCG levels double about every two days for the first four weeks of a normal pregnancy, then slow to every 31/2 days by six weeks. Those with failing pregnancies will also frequently have a longer doubling time early on or may even show falling hCG concentrations during the doubling period.
