Menstrual Cup?

So I’m 15 almost 16 and I have a kind of heavy, irregular flow. It skips months at a time and I have clots and it’s honestly scary for me since I’ve been having it for about 3 - 4 years (since the beginning of 7th grade, I’m currently a sophomore). I was wondering if I could get advice on if a menstrual cup is worth it. I wear night time pads and super sized tampons (when I don’t wanna deal with the pads) and I don’t know if i want blood on my hands if I can help it. The explanations are a bit weird from what I’ve seen already and they sound like something from a twisted movie ? How would I deal with it at school, would I have to wash it every time I took it out and put it in? It seems kinda complicated 😓 is it painful?
