Slippery pulse is a term used in Chinese medicine to refer to a pulse that flows in and out, like a pearl on a plate. There are many signs of a slippery pulse, such as impending menstruation, pregnancy, and dampness or food stagnation in the body. If a woman has a slippery pulse without other illnesses, she may be about to have her period or be pregnant. The diagnosis of which is the case cannot be determined by the pulse alone, but is based on the specific circumstances of the person, such as age, previous menstruation, the presence of early pregnancy, etc., combined with the appropriate tests. If a woman is not sexually active, she can observe whether she will have her period in the near future according to the time of her last menstrual period. If a woman is sexually active and has a delayed period, she can go to the hospital for a blood HCG test to check if she is pregnant.
