Bad smell

This is extremely embarrassing because this has never happened to me. But I just got off of my period like 3 days ago. Yesterday, I noticed this bad smell *down there*... I immediately jumped in the shower, I have good hygiene, I shower everyday. This smell honestly smells like something died. It’s not as strong as you’d imagine but it does resemble that smell. It’s really bothering me and making me feel disgusting. I have no idea what this could be. Nothing burns, itches, I have no weird discharge other than what it normally looks like. I’m stuck at this point. Has this ever happened to anyone?? 😫
