Too early for pregnancy symptoms?

On this app my next period is 8 days away, for the pass two days I’ve been getting super nauseous to where I take tums to help my stomach this time it woke me up from my sleep its 12:56am and I feel so nauseous. Now I don’t know if it’s too early to tell but I did have unprotected sex with my fiancé and yes he came in me on the 9th of this month and the 12th of this month, please help a sis out should I be feeling symptoms if I’m pregnant or tooo early?
