PMS Or early bfp symptoms?

AF is about 4/5 days away and because I can’t NOT test to save my life, I’ve been testing since 6 dpo and all have been bfn. However, the past couple of days, I’ve been feeling very gassy/not too “bloaty”, lower abdominal twinges, and excess cm. I’m not feeling cramping 🤷🏻‍♀️ could these be good symptoms?? Or bad?(AF)
