When to test..

Need a little input :) now 3 days late. We had sex during my fertile window (Dec15th-21st) but he pulled out (yes, I know about precum) and I've got 3 kiddos already all which I found out I was pregnant after being 3 days late.. I took a test today and it was negative (and I tested mid day which I've done in the past with accuracy) So. Should I try again in the AM or wait a bit longer?
