Okay so I’m 17, and I’m only able to fit in the mini tampons, I’ve tried the regular size one and it goes in but it burns and it’s so uncomfortable and it hurts, so I tried the mini ones and they fit perfectly and I barely feel it

Problem is, the mini ones says it’s for the lowest flow, and my flow is from medium - heavy so what can I do considering I cant use the bigger tampons for the medium flow? Could I just keep using mini ones for medium flow?
