Help please

Ladies... 😭 I need help. I’ve had symptoms for 2 weeks. This morning the clear blue digital said ‘Pregnant 1-2 weeks’ then I started to have a heavy bleed. I went to hospital. They did a blood test and said I am not pregnant and I am not having a miscarriage. They said the test is wrong. Yesterday I did a clear blue line test and that was positive. The doctor said my HCG level was only 3.3 and if I was pregnant if miscarrying it would be in the hundreds. Please help me. Tell me what ya going on. I’m at the end of what I can cope with. I’m confused and broken.
