I don't have that bullet, but I have "bruised" my clit from enthusiastic toy use. I take a break for a day or so, and things go back to normal.
If this bullet is causing you a lot of discomfort, try an other toy with a different type of vibration. I find "buzzy" toys tend to sometimes hurt while we play. While I have to really overuse a deep thrummy vibrator to get sore.
