Metallic Taste 6 DPO

This is our 4th month TTC #2. It has been over 5 yrs since I was pregnant with our daughter. I keep reading into every sign each month, hoping that it is the month. This morning I woke up and all was normal. 10 am I had some salami, and ever since then it tastes like i have been sucking on pennies. I have since eaten lunch, gum, snacks, flavored water, and brushed my teeth. Now it tastes like minty pennies.

Could this be a good sign? Am I reading too much into it? 6 dpo too early?
