So confused ??

I apologize for the second picture in advance. Me and hubby are trying to conceive, spotted for 3 days last month pink to brown. I took a test a week later neg. Then I took another test two days ago. Now I'm spotting and I read that u could still take a test while spotting so I took the third one today.  I don't know what this means? Could be a miscarriage and my hormones are still there? It's bright red blood so I just don't know?
