i need some help! quick!!

i tried putting a tampon in when i wasn’t on my period, ( i didn’t push the tampon in tho) i just put the applicator in. it hurt to put it in standing up but did it when i was laying down, i agreed with myself to actually push the applicator in ( which means have the tampon inside me ) when i get my period. i tried and i couldn’t do it, i didn’t know what i was doing wrong i angles it but something was blocking it, it just could go past, i needed it because we were gonna be running around finding easter eggs but i ended up using a pad and i honestly was so upset! i hate wearing pads but i wear them at night. and now i need them again in about like 1 and a half hour! please help me! what am i doing wrong !?
