dancingAccording to a study out of University of Göttingen in Germany, folks who see you dance in your Week 2 (which starts 8 days after the first day of your period) view you as more attractive than women on the dance floor who are in other weeks of their cycle. Why? Subtle changes in the way you move disclose that you’re in the most fertile phase of your monthly cycle, which is an evolutionary cue that attracts hotties like a magnet.

Not a fan of dancing? Then walk around. The same study found that your gait in Week 2 also subtly changes to boost your physical appeal.
