[TMI] What is this? Weird discharge?

Been seeing something like this for a week or two now. Unsure of what it is! The color used to be kinda mauve, but it’s gotten lighter.

According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> my period should start in a week.

The last time I had sex was two weeks ago without a condom, but we pulled out. I haven’t taken a pregnancy test.

IT ACTUALLY LOOKS MORE SALMONY/PINK IRL. The lighting makes it look yellow.
