Cervical mucus

Everything I read says I'm ovulating between the 5th and the 7th according to the first day of my last menstrual cycle. I have checked my cervical mucus but it is just wet and watery. It won't stretch at all. so am I not ovulating? I'm in my early twenties and read that most women my age experience 3-5 days of egg white cervical mucus. Advice??
