when to test?

Megan • Mommy to a little boy 💙 Aug. 2017
So my last period was the 3rd of September, the last date i had sex was the 25th. Earlier than that was the 18th. It is now the 5th of October and I am 2 days late for my period. I have early pregnancy symptoms. I'm nauseas, my breasts hurt beyond belief, I have food aversions, and fatigue. But I haven't had any implantation bleeding. When should I be able to test for an accurate result?
