Weird Question??

I heard that a “Metallic” Taste can be a sign on Pregnancy..... I don’t no how true this is.

But today I randomly got this metal taste is my mouth, it’s a taste that‘s hard to explain. It’s happened twice today and happening now and It has never happened before to me.

Have you heard about this and is it true? Idk... Just weird how this random Metallic Taste appeared in my mouth.
