Will CheckMate work on feminine hygiene products like panty liners?
Yes, the Infidelity Test Kit is routinely used by men to test feminine hygiene products for traces of semen. It’s simply a matter of gravity. If she has unprotected sex and then puts her underwear back on there is going to be an obvious semen stain either in the undergarment itself or on any panty liner type product that may have been used.
