Nasty smells?

Girls so I had my period right and it was my second 1 in 1 month for the first time but like omg idk if it was me but bro I kept smelling this nasty ass freaking smell omg it smells like period blood, raw meat, and garbage. And like whenever I wipe or something I don’t smell it on me but I’m off my period rn and I still smell it omg it stinks so bad but it’s not my cooter cat but wtf is that smell. And no it’s nothing around the house. It’s but omg it stinks so bad and Ik pregnancy can give you bad smells and I took a test and it came back negative but idk if I took it too early idk but ts is so weird I’ve never smelled anything like it.
