False positive digital test ?

So my “last period” was July 14 I thought I was pregnant because my period was 4 days late THE month of Aug my “period “was VERY LIGHT I took a test the day of my “period “ came it was a vvvfl as well as a digital it said “not pregnant “ my period lasted 3 days I took another

Tested days later and noticed a line still so I went to the doctor with the tested and showed them I went to the doctors so can I get blood work the urinalysis came back negative the dr her self said she seen the line in the test I brought with me ( mind you it was morning pee ) and did a walk in a appt all within 25mins of this at home test they doctors said she will call me with the blood results never did I called 3 times and left a message 5 /6 days passed I had a digital test I took it this morning at 1pm this afternoon (8/27/24 )when I woke up my boobs were very SORE. This morning I’m so conflicted because I called this morning and they finally told me my blood was negative So I told the lady Otp what happen she said that weird and you can you get a false positive on a digital test that doesn’t sound right to me for a digital test to be negative my hcg levels have to be high for a positive on this test

Any advice what to do please very confused on a emotional roller coaster today (very emotional )☹️
