pregnancy test

I had my daughter 6 months ago. I'm ebf and I had unprotected sex yes yes I know very stupid save me the rude comments 🙄 I'm on Nora-be and honestly I've been feeling off lately. I got a test but I honestly don't know when to test and when it'll be 99% accurate I haven't even started my period and I don't when I ovulated nor can track when to test when my af is due.. what do you ladies think?
