hey to everyone, i'm quite new to menstrual cups i'm still thinking of getting one. I was going to buy the fleurcup but i'm still a bit confused as to which size to go for (they have the small and large). I have 2 children but they were both delivered by c-section and i have a normal to heavy flow on the first 2-3 days of my period and the rest of the time its a normal to heavy flow. Which should i choose?
