BFN after 14dpo

Brianna

Period is late2 days and I tested yesterday at 14dpo and neg. I’ve been feeling so incredibly nauseous and have a Metallic taste in my mouth that makes me feel more sick I’m dizzy I just don’t get it. I just wish my period would come or I’d get a positive because this is driving me nuts. Has anyone tested at 14dpo and got bfn and still we’re pregnant?
