Consfused! Please help!!! HPT

I took a hpt at 8dpo and I got a faint positive. I took another HPT at 9dpo and it was a bfp. But I took another test this morning at 10dpo and got a bfn. I used the test strips from early pregnancy test.com what should I believe? I don't know how to make my doctor do a beta because they don't like to listen to the patient at all. So advice on how to make them do a beta or what I should believe would be wonderful!!!!
