Left over or new ?

Give me advice. I had my D&C 4 weeks ago, got negative tests 6/16 and 6/18, so i stopped testing. My symptoms started coming back 6/21, so I took a test 6/22 and they were positive. I retested 6/23 am and afternoon, then again this morning. My digitals and amazon strips are still positive (strips are faint) but my FRER aren’t progressing like they should. Is it possible to get random “bouts” of hormones still leaving from my last pregnancy? Could this be a new pregnancy? Chemical preg? So confused with what’s going on. Please give me your scenarios! Thanks for your help!

Dates are by strips
