Google "ovulatory mucus" or "vaginal secretions." It does sound normal, it's just that you didn't have it before because you were a little girl. There is a thinner liquid that is more like milk and a thicker liquid that is like clear, raw eggwhite, both are normal at different times of the month and both have functions related to either keeping the vagina clean or preparing the body for ovulation. Check out the topic and you will find you've probably got nothing to be concerned about.
