4 days late?!

Jody
So I'm officially fours day late I tested on the first day of my missed period and got a negative....nov 3rd I had my iud (the paragraud copper no hormones) taken out and according to glow my most fertile  days were the 3-5 and I had intercourse each day that week.... I have no signs I normally have that I'm going to start my period. But am kinda on the fence if my body is just still getting back track after the iud.  should I test again or just wait?
