Can anyone Relate?? late AF But BFN

Idk what’s going on...last period was June 28...according to Glow I ovulated July 19...Fiance and I were basically like rabbits from the 10th through the 22nd. (He came to visit me in Korea..Army life) i had what seemed to be implantation bleeding on July 25-26 light very light brown/pink spotting. Went away nothing else came. Had mild cramping on and off. Still do. Constipated! It is now Aug 7. Still have BFN. Showed the man over FT. He cried :(.

Should I expect AF to arrive soon?
