Home teat still positive after negative hospital test

Hi just wondering if anyone can advise or been in a similar situation?

Sorry its long ...........

Last week I had a positive pregnancy test, followed up by quite a few positive tests ( I was just checking) I used morrisons tests, early first response and clear blue digital. I had faint lines on the morrisons and First response tests followed by stronger lines on both a few days later, the clear blue said 1-2 weeks pregnant. I even had some of the cheap dip stick tests which had a result that got stronger although those ones aren't great. 6/7 days later I did another clear blue digital and it said 1-2 weeks pregnant again so I just put that down to only being a week passed ovulation the first time and that I must of then been 2 weeks passed ovulation when I took the second one. I'd also had some cramping nothing much that went away after a few days. 3 to 4 days later I had some light bleeding late afternoon nothing much, what I thought was implantation bleeding, it seemed to stop and then had a bit more that was brownish but stayed light then stopped but I was having cramping. I decided to get it checked went to A&E and had my bloods and urine checked. After 4 hours they asked me to do another urine sample as couldn't find mine but then managed to find it and said my urine test was negative so must be a chemical pregnancy, I'm certain when I asked if my bloods had come back that they said the urine test was negative so they didn't need the bloods 🤷‍♀️ whilst at the hospital I'd had more bleeding so thought they were right and accepted it. Since then I've had more bleeding but not as heavy as a normal period and the cramping has now settled to almost nothing but home tests are still positive 🤷‍♀️

This all happened a hospital whilst i was away so contacted my usual dr and they want to fo their own bloods as said i could still be pregnant any advice ??
