What does feeling funny even mean?

I never understood what that meant when girls say, “I just felt off and decided to test”.

Today I feel like a fat tub of lard, bloated, still tired, goosebumps, and feel all kinds of weird... like my eyes keep fluttering, I can’t focus and my brain seems to be going a million miles a min, lots of salvia in my mouth too 🤣 Lol

Am I crazy????

No I haven’t tested, waiting until I miss my period.
