I’m not on my period what is this...

Trinity

Okay so I’m only posting this because someone asked me if I was pregnant today and I was like no and they said they just had a feeling .... my period isn’t due for another 2 and a 1/2 weeks and I use the bathroom and see this. Honestly I wouldn’t be freaked out if that woman wouldn’t have said that today. But does anyone know what this is from I’ve never seen anything like it especially in between periods.
