Is this implantation bleeding?

*Posted on another group. Only difference is I was 9 dpo not 10.*

So for some background story shark week came on November 24-30. Began to cramp and spot from December 8-10. By spotting no where near needed a pad or tampon, blood only present when I wiped.

Glow predicted ovulation day on December 11.

9 DPO and began to once again lightly to moderately cramp again. Went to bathroom and noticed I am spotting again except so much lighter. Bleeding only lasted a few hours. 3 hours at most.

Now at 10 dpo, light cramping to none, areolas and nipples are sore and occasional nausea.

Could this be implantation bleeding??
