Nausea timing question !

Emma

I was just thinking of the timing I started feeling nausea , I started logging I felt sick at 8dpo , now I know that feeling sick is a symptom off both . My question being would 8dpo be too early to feel sick and more than likely be pms ( going by the you an implant between 6-12 days) ! I’m just fed up of symptom spotting ending in disapointment ! Thoughts ? X
