Do I Have A Vaginal Cut From Using A Menstrual Cup, And Is It Safe To Use It Again Before Healing?

Do I have a vaginal cut or not? A day or two before my period started I noticed a little bit of red/pink discharge. I had been wearing a menstrual cup so I’m not sure if because of that it had stretched and possibly made a small tear or if it was just a bit of blood from my period before it had really started. Do I have a vaginal cut and would it be safe to wear a menstrual cup? Or should I wait a week for the potential cut to heal to prevent possible infection.
