I put a super tampon in for the first time and im scared to take it out! help:)?

so my period flow is pretty heavy today. i used a regular and in about an hour it would be leaking already. so i took one of my mom's super tampon cardboard applicators and it hurt really bad to put it in. its already a cardboard applicator which makes it way harder to put in. right now i don't feel anything, which is a good thing, but im scared to take it out though, im not sure if i still have my hyem. i did alot of sport and im very flexible so it kinda give me some doubt i still have it. but im kinda scared to take it out later. any advice?? i know this sound kinda gross but i have my parents lube ( i know it is normal for my parents) should i sneek in and use that?? thanks :)
