Imperforate Hymen

I’m really worried, i think i might have an imperforate hymen. I’ve never ever been able to use tampons, and today i decided to look at my vagina to see what was going on, maybe i’m putting it in the wrong place, and i just couldn’t see an opening it was just nothing just like a wall. So i looked up a diagram of a vagina, and i saw one labelled “imperforate” and i feel like that’s what mine looks like. I could be totally wrong but i’m so so scared.
