AF a few days late, but bfn

Rachel
So my husband and I are loosely trying, we are 36, but we're living in different cities amidst a move for the past few months.  Weekends only make it tough to really plan to bd!  Anyway, my af should have started Tuesday and I took a test on Monday which was negative, but here we are, no af.  Should I take another test or is a negative that close truly a negative?  Thoughts and baby dust are most welcome!
