Over a week late, negative test 😔

I’m never late, for the last 7 months I’ve been trying I’ve had a consistent 30 day cycle. However here I am on CD 38 and nothing. I’ve had intermittent symptoms: nausea, constipation/diarrhea, heavy breasts and kind of tender nipples, some cramping, and so tired (I’ve been going to bed at 8-9pm) but they’re not like terrible symptoms.

I took a test yesterday afternoon and it was negative (with maybe a faint shadow line) but for being a week late shouldn’t it be positive?

Anyone have this happen and be pregnant? Should I go in for a blood test?
