6 dpo 7dpo is there pregnancy symptoms

Erin

On 6 dpo at night I was in bed sleeping and woke up really nauseous and went to the bathroom and didn't throw up then I got a little dizzy and had to sit down.I went back to bed and woke up again and felt nauseous again it was just on and off with no throwing up.On 7 dpo I was very dizzy today and my nipples feel tingly.Is this to early for pregnancy symptoms?
