Yellow cm

Has anyone gotten yellow cm, looks like ewcm but yellow before BFP or period? I’m 9dpo had a BFN this morning which was expected. My period is due on Monday or Tuesday I believe. I just had some yellow cm after going to the bathroom. I visibly remember this when I got my BFP with my son, this is my first cycle trying for #2 so I haven’t been super in tune with my body but I’m pretty sure I have only ever got yellow cm before I was pregnant, I never notice it before my period. I didn’t get a BFP until 11-12dpo with my son. Has anyone else experienced this? Have you ever got it before your period? Just curious and trying not to get my hopes up. Baby dust to all
