Help me, I might get killed for that 💔

Girls my last period was on 30 July and I finished on 4th of August, I had unprotected sex on 11 August and he pulled out he didn’t came inside me.

<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> said that my next supposed period should be on 23 August and now I’m 6 days late.

I did 2 pregnancy tests , the first one was on 25 August and it was negative, the second one was 28 August and it was negative also.

What do you think is going on?

I’m freaking out cuz I’m living in Middle East and I’m not married, being pregnant out of marriage is forbidden here, I might get killed for that and I can’t sleep well cuz I’m thinking all the time 💔💔💔💔💔

Is this normal?
