Possible yeast infection ?

For about the past month I have noticed my discharge turning yellow and extremely globby. It’s not watery at all and there is a lot of it. My vagina doesn’t really itch or burn. I am 31 weeks pregnant and am unsure if it’s hormonal or sounds like an infection. I’ve never had an infection before so I don’t know what to expect or what this could be. I will be asking my OB but it’s been bothering me.
