Urine turning red with salt is not necessarily pregnancy. Because urine contains about 1% of inorganic salts, such as sodium chloride, sodium phosphate, etc., after precipitation can precipitate light red crystals, so that the urine becomes red. Therefore, the reddening of urine has nothing to do with whether or not salt is added. Adding salt may just make the urine redder, but it is not necessarily pregnancy, and it is unscientific to use the reddening of urine with salt to determine whether or not you are pregnant. To find out if you are pregnant, you should test your urine with a pregnancy test paper, pregnancy test stick, or go to a regular hospital to test the HCG level in your blood, which is generally a more accurate way to determine if you are pregnant. If the test result proves that you are pregnant, you should take regular pregnancy tests to monitor the development of the fetus. Women who need to determine whether they are pregnant or not are advised to go to a regular hospital and take the test under the guidance of a doctor in order to obtain accurate results.
