Worried As Hell😣😩

AF still isn't here😣
I'm approximately 3-4 days late. 
Didn't have sex throughout my fertile week. 
But should I be worried if my boyfriend and I grinded naked and he might have pre-ejaculated? 
No penetration. 
He peed after his last ejaculation. 
But should I still worry?
I can't be pregnant😣😩
