Test date?

Erin
Hi I am wondering when should I take another test?
I did one a few days ago and I'm sure it was negative, im due 3/27 and I was late so it became 3/29 then 4/7
My ovulation according to glow was 3/13
I had brown spotting literally so little I barely noticed until the laundry a few days ago
Im unsure if I should waste another test?
