Now I'm really Nervous

Ok, so a while ago I made a post called "Am I Too Young", or something like that. I would recommend reading it first for some more backstory. Anyway I'm 13 and I was planning on sometime soon asking my mom for a menstrual cup. Tonight, she said she saw my period bag, or something like that, and that "You're probably not ready for tampons yet". Btw, I have been using tampons basically since I got my first period, even though I have only had two. I had already masturbated and, um, explored my body before my period, so I was comfortable and fine with tampons. Tbe thing is, now I feel like my mom will be shocked that I already have used tampons and maybe say that I'm too young for a menstrual cup. Sorry this was so long. I would really appreciate advice on this though, thanks. ❤
