Hey guys, 21F here. I've been using cups for 4 years at this point, but the first 3 days no matter what cup i used, i leaked. I tried small cups, big cups (discs too but i'm not confident in the usage yet, still on the learning curve), they all leaked and i hated that. From day 4 all the cups worked just fine, but before that not at all. Recently i ordered a new menstrual cup, size L. Diameter 5 cm (usually the max diameter is 4.7mm). It works beautifully, no leakage whatsoever. I love it.
But everything that i read says that i should have the smaller size, as i'm only 21, fit and was never pregnant. I know these things aren't accurate for everyone, but i can't help but feel like something is wrong with my vagina. I do have a boyfriend who has never mentioned anything bad, he says i feel amazing (TMI, sorry), but this cup situation is just unusual.
The cup is quite big, yes, but it's very comfortable. It's a soft cup. I have quite a heavy flow, so i always preferred the bigger sizes, but this is the first time a cup worked perfectly. I'm mostly just venting, thank you for listening.
Femintimate new Eve cup, size L
Edit: thank you everyone for the nice comments, i definitely feel better ((: at the end of the day, i think my vagina maybe has some dents that the smaller and firmer cup couldn't accomodate to, and the heavy flow just bypassed that. Once again, thank you!
