HELP AM I PREGNANT!?!

I had an period 8/28/2022 on 6/5/2022 me and my boyfriend had unprotected sex for literally 2 minutes(I know its still possible bc it was unprotected) because I was scared. I took a test 6/11/2022 negative. But I’ve been supper stressed since that day (i’ve heard stress can delay periods.) I haven’t had any symptoms I took a second test 6/20/2022 still negative . I took another test 6/23/2022 negative still. My expected period was 6/25/2022. But I took a test 6/24/2022 negative a few hours later I had very light flow bad cramping bleeding lasted 4 days a little bit of clotting as well. I took a test while the light flow on 6/25/2022 it was negative again and I took another this time digital 6/27/2022 still negative. Im really just worried because my flow was very light and wondering if stressed could have caused this.
