Implantation or Period?

I am cd 19, 6dpo and 11 days until expected AF. I have been tempting and today had a temp drop. I also had positive opks right at ovulation and we baby danced! I had a smalllll pink watery spot when I wiped this morning, just one time. Then nothing until this picture and that’s been all. What could this possibly be. I don’t have any bleed mid cycle. But our bodies make us wonder so I’m not sure! Help PLEASE 😫😫
