7DPO. Implantation?

Lena

I’m 7 DPO. And AF isn’t due till next week (sun/mon) could this be implantation? Second time today, only when I wipe. Nothing on the panty liner. On my second round of Letrozole (5mg, CD 3-7). Thanks!

UPDATE:

This was tonight...my cheeks and face have been feeling reading flush for a days now. This was when I just wiped
