10DPO metallic taste in mouth

Han 🌞🌻

All tests I’ve taken so far have been BFNs.

This morning I’ve felt slight twinges in my boobs, some slight pulling feeling cramps and have had this strong overpowering metallic taste come to my mouth. Ive brushed my teeth but it’s still there. Is this early pregnancy signs despite my BFNs? Never tasted this taste before. Sort of taste like used batteries
