What is this?

Has anyone else seen this before? My period was two weeks ago. And from my calendar today is the day of my fertile cycle. It could be possible that I already went through ovulating cycle earlier before. I’m irregular.

Is this implanting bleed or maybe something else?

No idea is a bad idea please nothing negative.

And DONT be THAT person who say go to the doctor clearly I know that just seeing other people ideas and such. Thank you!
