Could this be the month?

My cycles vary my shortest cycle being 22 days and my longest being 30 (only happened once) the average is 26 days. I had very light pinkish brown spotting yesterday at 12 DPO only once when wiping and slight cramps the night before. I’m currently 2 days late according to my chart but I’ve been late before (on my 30 day cycle) I’ve been sick with a cold since 7 DPO and I don’t want to get my hopes up until I’m past the 30 day point. I usually tell my SO when I’m expecting AF and when I’m late and how I’m feeling but this month I haven’t said anything to take the stress and pressure off. When should I really get my hopes up? Could this be the month? Should I wait another 7 days before testing?
