I didn't switch to a cup until the last couple years or so of my period, but it was so liberating when I did. It took a long time to be willing to try it. It requires a lot of handling one's parts, but it's worth it. It cuts down on mess and waste, and it made me feel like what my body was doing was normal. Also it was kind of cool to be able to know how many ounces were coming out.
Before that I used tampons.
