Implantation bleeding??

So I am 8 days post ovulation. But Friday I had bright red spotting (not a ton, just when I urinate and wipe), then yesterday has very very light spotting which was darker brown (only once yesterday). Hubby and I bd every day for 4-5 days leading up to ovulation and one time after. I was cramping too bad on ovulation day for bd. It was like sharp stabbing pain in my uterus and made me dizzy. No more cramping since ovulation day, and no more spotting today. Could this possibly be implantion bleeding? I’m not predicted to get my period until the 26th!
