14dpo, no af, bfn

I’m 14dpo, this is second day af is late. (Periods are very regular 26-27 day cycle). Sore boobs, nausea, and fatigue are my only symptoms. But I still continue to get bfn. Could I still be pregnant? I usually have cramping and some brown discharge the day before af should arrive. And I haven’t had any of that.
