Snot like light yellow discharge

I am 5w4d and after I went to the bathroom I noticed a bit of snot like (light) yellow cm mixed in with my regular white cm. There is no smell or itchiness or pain and I sometimes used to get this kind of cm before my period in other cycles. I am freaked out that it might be the start of something bad and was wondering if anyone else experienced this ? I have a doctor appointment next week but I am going crazy waiting and wondering...
