Is this normal?

I have s ton of discharge just like I did at the end of my first pregnancy. This time I'm using panty liners. I've noticed a super light yellow tinge to the discharge. I'm really unsure if it's just disharge mixed with urine leakage or the actual discharge color. I'm 33 weeks and this kid is LOW and ON my bladder. I'm kind of lost. Should I bring it up at my appointment friday? No smell btw and it's not nearly as yellow or as much as I've seen in women with BV. Just curious of your thoughts.
