Pregnant?

So first off I don’t want to be overdramatic but I’m afraid I might be pregnant, I have been on and off different birth control pills because they have been driving me crazy! But I have been off one for a month and haven’t gotten my period since I’ve gone off of it. I have had sex with my boyfriend a few times during this past month and we haven’t used a condom but we’ve used the pullout method (he’s never cum inside me and struggles with erectile dysfunction and can’t keep an erection with a condom) Anyway, my period is now 6 days late according to the app, it’s usually pretty accurate. I took a pregnancy test when my period was 2/3 days late and it was negative. Did I take it too early? Am I just being paranoid? How long until I should take another test? I’m a little paranoid, any advice would be great!
