I let my boyfriend come in me for the first time (never had come in me before), and it smelled weird and I had strong smelling discharge that had a yellow tint. That was almost a week ago. The discharge has since gone away but the smell is still not normal, it’s not as strong but it’s still there. It’s kind of sour and bad smelling. Is it possible I could have BV? Should I take medication in case I do or should I wait till it goes away?
