When women understand what is going on with their own bodies, they can take their health into their own hands. Our vision at kegg is to equip women with a deep fertility insight to empower them to make decisions about their own reproductive health.
Kristina, the Founder, was shocked when her OB/GYN doctor told her to track her fertility by checking her vaginal fluids daily with her fingers. All she wanted was an accurate way to track her cycles naturally, but the au naturel way only left her more stressed and worried.
We live in a world where autonomous cars take over the streets and robots perform surgery and yet, women are still being told to use their fingers to access their fertile window. The only other device that measures cervical mucus, which is the golden metric for cyclical conception, is a metal probe (20 inches long) connected to a small computer with cables.
Its time technology caught up with us.
