AF due May 18th

Hi ladies,
​As the weekend slowly approaching I'm getting extremely anxious to test! I realize you can't get a BFP unless implantation happened. Based on a calendar today should be the day. I woke up this morning with a dull lower back pain and then menstrual type cramping. I also checked my cervix and it's pretty high, open, somewhat soft and with wet/sticky cm. Anyone else experiencing anything similar?
