11 Days Late🤦🏽‍♀️🙄

I took three Walmart .88 cent cheapies on day 2 of missed period, day 4, and day 6. The first one was negative and the other two came back as a vvvfl. I’ve had no spotting or bleeding since last cycle. Usually have a 28 day cycle. But I’m on CD 37. Should I make an appointment for a blood test? Or will they not see me yet?
