Possible chemical pregnancy?

By week four, I was feeling nauseous, I couldn’t stand meat, by week 5 1/2 I was having brown spotting, which two days later turned to bleeding with clots, cramping felt normal, not to bad.. bled for four days and now it’s brown again.. but there was clots, my nausea is still somewhat there, still not a big appetite.. but still bleeding a bit with brown spotting, pregnancy test came out like this, faint but hubby sees it to.. do I need to see a doctor or does it run it’s own course?
