Something comepletely flat and red stuck in my eye?

[GeauxHomeLittleD]

Hi all.
So I woke up with this small completly flat and red thing in my eye? When I try to pull my lower eyelid away a bit, the thing is just completely stuck to my eyeball so I can't grab it. I tried rinsing a few times, doesn't do it either.

Would this be a problem if I ignore it , will it go away on it's on?
Or how else to try to remove it at home?

What if I'm unable to remove it ?
Could it be some eye injury as it's red ? Though seems unlikely.

Thanks

One time my ex got a tiny metal shaving stuck (embedded) in his eyeball. We were young, had no insurance and couldn't afford any medical bills. Not even our friend (an optometrist) could get it out with the proper tools. It bugged him for a while but eventually his eyeball pushed it out on its own. He never had any problems with that eye after, to this day he doesn't even wear glasses.
