Nausea during implantation?

Danielle

I know it’s NOT a pregnancy symptom as it’s way too early. Just wondering about implantation causing nausea? I’m 6-7dpo and yesterday and today experienced nausea and tonight mild heart burn which I never get. Again, I know there’s no HCG/pregnancy, to cause this, but can implantation cause this? This is not normal for me during my cycle.

Ovulation confirmed via LH Strips and BBT.
