Reassurance

I know I'm probably being irrational...
I had my period last month, but it was lighter than usual and I was having weird symptoms 
My boyfriend and I had sex outside of my fertile window before that, we used and condom and he didn't even ejaculate we did it for five minutes and checked the condom for holes with water afterward...
I even took a pregnancy test to make sure I wasn't pregnant and it was a strong negative at 19dpo with no faint lines.
Now my period is almost do this month, about a week away and I'm nervous it won't come. Am I worrying for no reason?
