Metallic taste and spotting....?

So yesterday and today I’ve had this bad metallic taste in my mouth. I’m not sure that I’ve ever had it this strong/last very long. I also was spotting some yesterday (not very much).

We haven’t done anything for a few days but it would have been around the end of my period. No protection- we hardly ever use it unless it’s a high percentage day. I haven’t gotten pregnant in the year or more we’ve been doing without.

I read online it’s possible for metallic taste to be a sign of pregnancy? Is this common for you ladies? The spotting I think I’ve had before at times. Opinions?
