Wellness tech companies are increasingly interested in bodily fluids like blood, urine, sweat, and saliva. At CES 2026, it's time to add menstrual blood to that list, too. Health tech startup Vivoo just announced the FlowPad, a roughly $4 to $5 menstrual pad that doubles as an at-home hormone test for follicle-stimulating hormone (FSH). Users will be able to either view the results directly from the pad or take a picture with the Vivoo app to get more insights.
