5 days late

Amanda
Hey ladies I'm 5days late and finally just had blood work done to see what was going on, Dr said it's less then 5 which means I'm negative. So I'm pretty sad right now and not sure how I could have missed my window since me and hubby had sex every day for three weeks starting before ovulation til way after. Said its probably another cyst but that if I don't start in another week to take another test to be sure. Has anyone else had this and then turned out pregnant?
