This morning, AF is three days late. I haven't tested due to too much going on.

However, this morning, I've had the most strange tingling/metallic sensation in my mouth. It's like my mouth is full of metal, it doesn't taste bad, it just feels weird.

I am wondering if something I ate caused this?

I had a TV dinner and orange juice for breakfast. I thought maybe the orange juice, but after looking it up, orange juice helps get RID of metallic tastes in mouth.

Am I going crazy? Could it be something I ate? Or is this a sign?
