Has anyone ever got a bfp after 13 dpo/14dpo

Has anyone ever got a bfp after 13 dpo/14dpo? I am 1/2 days past my 26-28 day cycle. I have never been late and get horrible cramps, I can usually feel my period coming 2 days before. I have had some mucus looking spotting 3 times the past 5 days (drops of dark red and then yesterday light light pink) . I just took a pink hcg strip test and it looks negative
