Is this a yeast infection?

I’ve been having vaginal discomfort for about a week now ( like a slight burning), and when my husband and I have sex there’s a STRONG SMELL. Obv. Comming from me. It’s so embarrassing. It’s thick and creamy, and has an unpleasant smell. Prior to this, we’d have sex and this discharge would not come out, it was all clear and juicy wetness (lol 🤷🏻‍♀️) so it’s definitely weird to me. I had a yeast infection once a couple years ago, same symptoms but the discharge was chunky. I’m about to use this Monistat 3 out of desperation‼️‼️
