9dpo symptoms but BFN

Stevie

Cramping in left side 7dpo and 8dpo

Nausea on 7dpo and 8 dpo

Metallic taste in mouth 7dpo, 8dpo and ALL DAY 9dpo

Absolutely exhausted!!!

taken 2 tests and both BFN. I would never usually have these symptoms pre AF. Anyone else had these symptoms on these days with a BFN that’s eventually turned BFP??
