Under normal circumstances, urine is light yellow, when the body has insufficient water or urinary system has lesions, the color will appear abnormal. However, there is no scientific evidence that urine with vinegar turns red to detect pregnancy.
For women with regular menstrual cycles, you can determine whether you are pregnant by taking a urine pregnancy test when your period is delayed, and if it is positive, consider the possibility of pregnancy. If the test is positive, pregnancy is possible. If the test is negative, it does not necessarily mean that you are not pregnant, but it may be that you are pregnant for a relatively short period of time, so it is recommended that you take another test in a few days. You can also go to the hospital for blood tests as well as ultrasound tests to make a clear diagnosis under the guidance of the doctor.
In addition, if there is a change in the color of the urine, you should go to the hospital in time and follow the doctor’s instructions to do a detailed examination. Urine with vinegar to determine whether pregnancy is not scientific, there is no theoretical basis.
