help please! I'm so scared

Okay so I'll try make this as short as possible.

I'm a teenager. I have a boyfriend. This weekend we had sex. It was on the 24th of November. I had my last period on the 4th and ended on the 6th. He did not cum inside me, he pulled out and cumed about 30 to 40 sec after. I live in a Muslim country (UAE) and birth control pills and contraceptive pills are illegal. What are the chances if me being pregnant?. Also my chance of pregnancy was 3% (according to Glow). My next period is expected to come on the 4th of December. I am a Christian and I know I did wrong. I'm so so so scared of what might happen. I honestly just need help right now. Pls help me I'm extremely scared and ashamed of myself
