I am new to this and hardly understand it. Everywhere I read it says different things about ovulation. You ovulate when the temp dips, you ovulate when the temp dips and stays high three days in a row. Can someone tell me when I ovulated? Also, since my cycles are only 25 days (Glow says I should start on the 20th), when should I test? Today the temp is a little lower then previous temps, does that mean I'm not pregnant?
