Anyone have a neg HPT but pos bloodtest?

AF was due Sunday. I've gotten it every 26 days like clockwork for the last 11 months. Now it is 4 days late. I've taken 5 HPT's over the past 5 days and went to see my OB Tuesday with a negative test there as well. I went this morning for a blood test to see what's up, but I'm so skeptical. I got BFP the first test with DS! Anyone have negative HPT's but a positive blood test? Thanks!
