evidence: The theory behind the salt test is that when a pregnant woman’s urine is mixed with salt, it will clump and appear to be "milky" or "cheesy" in texture. This is believed to be due to hormonal changes that occur during pregnancy. While the salt test is not scientifically proven or endorsed by medical professionals, many women have claimed that it accurately detected their pregnancies. [...] Using salt as a homemade pregnancy test is a popular alternative method for detecting pregnancy at home. This method is based on the reaction between salt and the hormone hCG (human chorionic gonadotropin), which is only present in a woman’s urine during pregnancy. [...] One possible substitute for salt in the pregnancy test is baking soda. Baking soda, also known as sodium bicarbonate, can react with the acidic content in urine to produce a bubbling effect. Although this reaction may not be as conclusive as a positive or negative result, it can indicate a potential pregnancy.
