Weird smells 👀

So anyway. My period blood smells REALLY sweet. And then my cooch just smells gross? Idk how to describe it, it honestly kinda smells like poop, mixed with something else. And this seriously isn’t a troll post. I take a shower everyday, I change my pad like every 3-4 hours. I don’t use soap to clean down there either, just water. It’s never been like this before, could it be because of my birth control???
