Metal Taste In Mouth?

So I was having dinner and I said out loud "I can taste my fork"

I never had that before - so I got a new fork, same thing. I started picking up my food with my fingers (classy I know) and again same thing!

My mouth tastes like it's full of metal! Or like a coin is just sitting in my mouth.

I took a pregnancy test today and it was negative - BUT I only took the test because I just had a FEELING I need to- my urine was very diluted, almost clear - I know that was pretty much a wasted test but I caved.

AF should be here in 2 days - do you think this is a sign of pregnancy, has anyone experienced this?

TIA
