Tampons not working?

For the people who leak through tampons (despite less than half of it being soaked) feel for the opening of your cervix. 
I've always had this issue. Then, when trying to find my cervix I felt the opening, but I wasn't centered. Upon research I realized that because of the position of a tampon, it will not work with a tilted cervix. 
The good thing is we can still use menstrual cups! I really recommend them, even if tampons work for you.
