TMI pregnancy discharge question

Is it normal to experience a lot of discharge around the 26 week mark? I’m going through like 2-3 panty liners each day for the last couple of weeks and when I change them they are sometimes tinged yellow. I’m pretty sure it’s not urine, I smelled it and it was mostly odorless and very watery/absorbed into the pad.

It only just occurred to me that it could be amniotic fluid, I just assumed it was normal. I’m going to ask my doctor at my appointment next week, but I’m a little nervous now.
