I’m am so confused….

So my last period was September 7th … so which would of meant I ovulated the 20th… I started bleeding on the 29th thinking oh implantation 🙏🏼? But today I had some tiny clots :( I got a faint positive on clear blue but on digital clear blue said not pregnant… I also took cheap dollar store test and were also faint positive… i am not supposed to start my actually period until the 4-5th of October…. I think I’m out this month or an early miscarriage :( results will be done on Monday and again the following Thursday to see if results for hcg show :( anyone have an experience like this?
