To complete this goal: Buy and use a menstrual cup for two menstrual cycles.
Why? I don't really like tampons or pads. They leak, I forget to change them or it's inconvenient, and I'm always running out. The cup seems like a great alternative, and I'm not freaked out by the blood, so no problems! (Sorry if you're squeamish about this stuff. It's really not that big of a deal, though. Happens to all women at some point.)
