2 positive HPTs, a few days later NEGATIVE blood test, then 2 days later POSITIVE first response digital?

So bizarre.. This week has been crazy. Okay so my period was due 11 days ago, I'm ALWAYS regular. So I took 2 HPT both faint positive , different brands. So a few days after my missed period, went to tge doctor to get bloodwork to confirm. He phones me the next day and said, your NOT pregnant. I was shocked, I've been nauseated and exhausted, had implantation bleeding. So then I thought well maybe they were evap lines, but they showed up within the time limit. So yesterday, 2 days after negativeblood test I decided to take a digital test just to make sure.. So I did and within 2 MINS, a big fat YES+ !! I couldn't believe it! Took it to the doc and said " see! I'm not making this up!" he was confused, and said maybe the bloodwork was a lab error, sent me for the more sensitive bloodwork, and I'm waiting.. What do you think??? Pregnant??
