Confused

Ann • 🌈 hoping for my rainbow
6 days ago I had a couple spots of red blood which my fellow Glow ladies suggested was ovulating bleeding. Shortly after that I had EWCM and a positive opk. We BDed every day in my fertile window. This morning I woke up with achy cramps in my lower abdomen/pelvis area. I was wondering if this could be from implantation or possibly my AF coming ridiculously early.
