Nausea .. 5/6/7dpo .. too early for pregnancy sign?

[fizzyblush]

Hello ladies

Nausea at like 5/6/7 dpo is too early to be a pregnancy symptom isn’t it? If it isn’t a early pg symptom what is it? I don’t even know if implantation could have happened by this stage ? Seems too early for that! What hormones are at play before implantation? Or maybe it’s all in my head ?

Anyone else feeling similar ? / could shed some light on the whole nausea symptom that happens early?
