Early pregnancy?? Help!

Cierra
Hello everyone,
 So I'm kind of freaking out right now. Me and my boyfriend had sex June 30th (the day I ovulated). We did the withdraw method and he also fingered me with his semen. Now I'm 8 days dpo (days passed ovulation). Right I'm just experiencing light cramps and hot flashes. My period
Isn't due until July 17. 
 
I just wanted to know if this a early sign of pregnancy??
