What’s the best way to know how strong or weak my vaginal muscles are? After assessing the strength of my vaginal muscles, how do I determine which cup would be best based on my vaginal strength? 

I urinate 4-7 times a day, which 7 are days when I experience my cramps on the 1st day of my cycle and that makes me go to the bathroom more. Would a soft-medium be a good choice?
