Does anyone smell butter?

Okay so TMI but does anyone else’s discharge/vagina ever smell like freshly buttered popcorn? It only happens when I start pms but my god it’s a strong buttery scent. I feel as if others around me can smell it. I’m terrified someone will sit next to me and say something along the lines of “does anyone smell popcorn?” What can I do? I take a shower every other day if that helps
