I'm 15 and I really want and Need to use tampons(I'm a horse rider and pads get stuck very uncomfortably,Plus other reasons) but my mums against it and my sister is too unless I can get a yearly test for cancer or whatever. I've nicked one of my sisters😳 and I've got it in my period stash but I'm scared to use it...... Would I be able to get a test now and then?
