9dpo period is due in 5 days negative test but crazy symptoms:(

Br

I tested this afternoon with first response and it was negative, is it too early to show?

My period is due in 5 days, I ovulated on the 27th.

Today just now I got extremely light headed, I woke up this morning nauseous and have been extremely tired these past few day.

Has anyone ever experienced similar to this???? It’s driving me crazy I do not feel like myself at all and he fact that I tested negative worries me!
