How long to wait to see doc?

Jessica

I've had some unusual symptoms this week and so I took an early test this morning. It came back with a faint but definite line. I'm only about 11 DPO and after previous disappointment I'm trying not to get excited yet. I intend to test again the day after I'm due AF, but just wondering how long you would normally wait to go see your doctor for a blood test confirmation?
