5 days late, bfn, is there still a chance?

Has this happened to anyone before? Im 5 days late today tested and bfn. I have regular 28 day cycle. I dont really have any symptoms other than I been feeling bloated, emotional (but that could be with everything going on), I have had this cramping on my left side on and off but not so much today. No spotting at all. Maybe some slight nausea? My stomach been a little uneasy but again idk could be anxiety.

Has anyone been this late before and got a bfp later on? Am I out? Idk what to think anymore.

I used the opks this month as I do every month im not more stressed, Im actually way less stressed lol except for now lol. maybe I ovulated later than normal and missed it? Idk if its normal to completely miss a month if your regularly normal thats never happened before.
