Implantation or ovulation?

Hi all,

New to TTC!

My cycle is sort of wacky sometimes so I really am not sure if I’ve ovulated yet. I got my last period around 8/28 but have had the EWCM recently too! The apps say ovulation should be this week but I haven’t had any peak test results.

In the last few days I’ve been sweating, like excessive, skin is always clammy, even when I don’t feel hot. I have on and off short headaches, a few minor cramps and some pelvic pressure today. When I peed I wiped and found this.

Could this be implantation? A sign of ovulation even if tests aren’t showing it? We’ve been BD almost daily for the last few weeks
