so stressed out

okay I'm officially 2 weeks late and no sign of getting AF. last week I had light pink discharge for always 5 days straight. I've taken 3 pregnancy tests and 2 of them have had a really faint line as in many people who have seen them have said they don't see the faint line. I've never missed a period before and especially this long ... should I go ahead and go for the blood work to confirm?
