Ok so is this a piece of my mucus plug??

Okay, so I know this doesnt look like a mucus plug. If we're being honest it looks as if I just had sex, then pooped, then wiped. BUT... I haven't had sex since yesterday and I wasn't "turned on" and I didn't poop. When I wiped it was from peeing. I lost a piece of my mucus plug 3 weeks ago and it never went anywhere- that pic is obviously part of the plug. I'm not so sure about this one. What do you guys think?! Here are photos of the other photo and then of the one just now. I'm 39+6.

This is from 3 weeks ago as a result from my cervical check.

This one is from just now.

This pile was also in the toilet when I lost a piece 3 weeks ago. Wasn't really sure what it was bc I DID poop that time, but that doesn't look like poop to me. Either way, I lost that at 36 weeks and there were never any other signs until now. No blood at all.
