Confused!!! Any help

I have a normal 28 day cycle have had since I started. I was due to start on sun, didn't start til wed, and normally af lasts 7 days. Heavy to start then tapers off. This time not heavy at all and ended this morning, so 3 days. Sorry tmi but no clots at all which is also unusual. Havent tested yet, waiting a few more days. Have any of you ladies had anything similar and still got a bfp!! TIA
