I just started to use a menstrual cup and i noticed a slight discomfort on my lower back and/or abs when using it. I dont experience cramp or lower back pain during my period before this. After removing the cup, the soreness would go away.
Is it because my vagina is still not used to the cup that it contracts more? Or simply because of the cup that is not suitable for me? Im currently using Organicup size A
