What does it mean when the rabbit dies?
When urine from a woman in the early months of pregnancy was injected into immature female mice, their ovaries would enlarge and show follicular maturation. The term ” rabbit test” was first recorded in 1949, and was the origin of a common euphemism, “the rabbit died,” for a positive pregnancy test.
How did they use rabbits for pregnancy tests?

How did they test for pregnancy in the 1940s?

When did they stop using rabbits for pregnancy tests?
In the 1960s, scientists ditched the animals entirely, turning instead to immunoassays, or tests that combined hCG, hCG antibodies, and urine—if a woman was pregnant, the mixture would clump together in certain distinctive ways. While women no longer needed a frog or a rabbit, though, they still needed a doctor.

What color is your urine when you are pregnant?
The more fluids you drink, the lighter the color of the pigment in your urine. The less you drink, the stronger the color. “For example, urine looks paler during pregnancy because there’s a 50 percent increase in blood volume, so the urine tends to be clearer and more diluted during pregnancy,” Dr. Kaaki says.

If neither sprouted, she wasn’t pregnant.
