I'm a twenty year old college student who has decided to buy a menstrual cup. I have seen the options offered, and from the reviews I've read, the Ladycup and the Lunette tend to be the most comfortable. Apart from occasional 'private time', I am a virgin but I think I have a good sense of how my vagina works. On my period, I tend to have a very heavy first day with the flow getting thinner and lighter until the 7th day when it all ends. I want to get a cup that can hold a large capacity, but at the same time I don't want a cup that is too narrow or too difficult to put in. So, I'm a bit stuck. I've looked at the capacity charts, but unfortunately I do not know exactly how much blood I let out during my period. Any suggestions?
