Early ovulation? Confused

TMI alert! So just had af end yesterday (cd7) and all I had yesterday was one spot when I wiped, paired with cramping in my upper abdomen (not pleasant). I also started clearblue ovulation testing and yesterday was nothing. Then today I have a flashy smiley face, still having the cramping. But my husband and I did the deed and now I'm having spotting again, red not brown so that means fresh blood? So was af not over, am I really getting ready to ovulate?
