What is up with this discharge?

Ok so yesterday at 6DPO I had light pink discharge when I checked my cervix (sus me I know it’s bad) and I chalked it up to maybe possibly being a scratch I didn’t feel bc I have acrylics.

Today at 7DPO I’m crampy and my discharge is YELLOW with the tiiiiiniest tint of brown. Not an infection- cross my heart.

What the heck is this?!?
