Help me understand -- Pregnancy

Okay. Yesterday I had sexual intercourse with my boyfriend. We did not use a condom and at one moment he did not pull out. I tried my best to find birth control in my area for morning after -- sadly no luck. I did a CM check, it was clear, watery but light amount. I'm freaking out and hearing tips left from right but sadly, I'm still confused on how to do this .. I have so many questions. When do I take a test? What are some early signs? Someone help me. I need to know what I'm doing that way I wont be so stressed.
