Terrible Cramps!!!!!

Tinille

Aunt Flow is due on Friday 9/1. I took a test yesterday at 9 DPO and one this morning at 10 DPO and both tests were BFN! Now I'm having terrible cramping but no spotting but creamy/sticky cm. Could I be implanting? I'm so confused. Want it to be my month. My cycles are very regular, 25 day cycles with 5-6 day bleed.
