Should I test?

Samantha • TTC baby #3 (1st planned)
What I considered af was a day and a half light bleeding with a few small clots then 3 days of light brown spotting.. Ive have a 28 day cycle since I first started my period 13yrs ago so this one confused me... I took a test 11 dpo and BFN, but I still feel weird... I did have af but it wasn't normal for my body.. I'm just confused and I want this so bad but I don't want to waste tests... anyone been in the same boat and receive a BFP?
