Metal taste in mouth

Brianna • 26. Married. Happy. TTC #1. 1 miscarriage, 3 failed IUIs. Male factor infertility. Starting IVF Summer 2020. Foster mama.

I am 12dpt and 10dpiui and I have been having a metal taste in my mouth for 3 days now. It comes and goes but it's around for most of the day. It's really gross and I have no idea what's going on. Could this be a symptom of the trigger shot?
