Need your input ladies🙏

So run down...

Was supposed to get my period on the 16th. Instead dark brown blood and clots only when I wipe. Lasted day and half....

Fast forward on Aug 20th faint line positive test. Aug 21st faint line positive. On the 22nd first morning negative test. Was that the chemical on the 16th? I didn't even know I was pregnant until the 20th. The only reason why I tested because I still didn't get my period. I'm so confused! Never been through this. Any help will be great. Can't go to Dr due to change in insurance. Process of finding one
