So Confused

I took a couple first response hpt and they were all postitive, bought a digital EPT it was negative ... Went to have blood work twice, it was negative both times... Then I started bleeding, so I figured I was getting some false positives. The last two days I took 2 more first response tests and both came back positive 😑 I have no idea what to think & the nurses at my clinic are no help! They just said "blood test trumps hpt any day, so you are definitely NOT pregnant & I have no reason to believe you are pregnant!" Very rude and not helpful as to why I am getting so many positive hpt! I would be about 4 weeks right now ....
