TMI..”down there” smells😳

So I’ve had the common heavy discharge most pregnant women experience and up until Sunday it smelled normal. I don’t smell it on purpose mind you, I just CAN because it’s THERE. Anyway, it completely changed and this is weird, but it smells like cat pee/dirty litter box down there now. No other weird symptoms, color changes, etc. I’m 32 weeks today. Is this a thing that happens..?? It really doesn’t seem like I have an infection or anything..but wtf😓
