If there is a blood clot, it does not affect the use of tampons. In addition to normal menstrual blood, there are usually clots or endometrial shedding and other phenomena during the physiological stage. Moreover, the tampon itself will only absorb the liquid-like menstrual blood, and the mucous membrane of the clot that is discharged in a slightly solid state will stick to the tampon slightly. They will drag out when you change out. This is the same as using tampons, these will adhere to the surface of the tampon and will not be penetrated.
