Sayang, rasa macam ni memang boleh jadi tanda-tanda awal pregnancy ke, tapi sebab last period mu 1 Jun dan HPT masih negative, might be good idea to test again dalam 2-3 hari or better lagi go see your doctor untuk darah test, way more accurate than urine test, especially kalau timing masih awal. The cramping and egg white discharge boleh jadi ovulation je, atau memang pregnancy symptoms, but only a doctor can confirm based on your full history.
