can someone tell me what’s going on?

(tmi picture ahead) these past two days i’ve been spotting a lot. i typically don’t spot between periods. for context: my period just ended last wednesday, i’ve been off birth control for about two weeks now, and i took a pregnancy test yesterday and it came back negative. but i’ve been feeling nauseuous all week and having horrible mood swings and stomach issues. after a negative pregnancy test, i thought i was just ovulating until i went to the bathroom earlier and saw this when i wiped. i’m gonna make a doctors appointment to run any extra tests and see what’s going on fr but i wanted to see if anyone had any further insight.
