As your fertility level increases, it will become clearer and eventually resembling raw egg white. During Ovulation or ‘Peak Day’, the CM will be relatively abundant in volume, its texture will become very watery and slippery and it will be highly stretchable in nature.  Try for Boy only on those days when you are experiencing ‘Peak Day’ symptoms. Chances of conceiving a boy are best within 12 hours before the Ovulation occurs.
