how long does it take preganncy symptoms to occur

I had unprotected sex on this Canada's day which was my first time. I felt his penis get intense when we were in the middle of doing it. Then he pulled out afterwards. I started to spot 4 days later and have been feeling nauseous and very tired the last 9 days. I have had sex once and I'm worried I'm going to be pregnant.

I thought it was my period but I was normal the first day then spotting the next 4 days. How early can I test. I had sex 9 days ago.
