What is going on

March 22 - positive first response urine pregnancy test

March 24 - positive first response urine pregnancy test

March 29th - light pink bleeding throughout the day positive first response urine pregnancy test that night

March 30th - heavier bleeding bright red small stringy clots on and off. Negative blood test level 1 hcg

March 31st - lighter bleeding still red no clots

April 1st - back to light pink bleeding positive first response urine test.

Has this happened to anyone before? My doctor said since my hcg measured at only 1 I should not get a positive urine test but I did... I’m so confused 😭
