Yellow mucus 30 weeks

30 weeks tomorrow and last night there was a yellow-tinged thick mucus on the toilet paper.

I have had a lot of thick mucus this pregnancy, especially after intercourse, but it has been a few days and is always white.

I also noticed a little yellow mucus on my bed sheet this morning (sleep commando 🥺). I haven't noticed a funky smell to it. Should I be worried or is this normal?
