Someone please help..?

I’m 13dpo today.. my bbt is still above coverline (it slightly dropped 2 days ago and it went back up) so I don’t think it’s af.. my af has been coming on usually cd30-31, but because I ovulated on cd14 this cycle, Glow predicted my af to begin tomorrow. I went to the bathroom and I have this light pink spotting.. is this possibly implantation? This morning my cervix was high when I checked. I also posted my chart below too. Thank you in advance.
