CD 38 no BFP no AF

Ma

I am between 8 to 10 days late, I tested at CD 36 BFN and now I am scared to test and plan on waiting another 4 to 6 more days before I test again. If negative and no AF I will see a DR which will be hard because I just moved to Spain and getting an appointment with a specialist without a positive test will be hard. I am so overwhelmed with not knowing and yet it happened when am not back in NY where I could have done the test myself 😭

Either way I just want to know

Any other person experience something like this?

Any help will do thanks
