Positive home tests but negative blood test

So me and my partner have been trying for a bub for close to 6 months now. Recently I've had multiple positive home tests. Different brands, both normal and digital tests. All have come up positive and saying I'm pregnant. However, I had a blood test and it's come back saying I'm not pregnant and I'm absolutely heartbroken. I showed my doctor my positive home tests (there are 7) and she said it must be false positives... I never thought it was possible to have so many flase positives especially from a variety of brands and both normal and digital. She's refusing to do a repeat blood test. I'm due for my period and I've only had light dark spotting when usually it's heavy and bright red. I don't know what to do. I'm completely heartbroken that I got a negative blood test. Should I see another doctor for repeat bloods? Should I ignore the multiple positive home tests? I'm at a loss. Any advice would be appreciated because I don't know what to think right now. Has anyone else been in this situation? What was the outcome? Has anyone got any advice? I've never posted on this app before but I just needed to get this out there and tell someone before I lose my mind.
