Ammonia smell

Hey guys !! So me and my boyfriend just had sex about an hour ago and almost immediately after I noticed I’m bleeding a little bit and I’ve been smelling a disgusting smell of chlorine for some reason but I didnt smell it until I stepped outside. Mind you it’s snowing and freezing outside and I’m smelling chlorine and for some reason I also smell citrus when I was outside as well. Anyone might have a clue as to why I might be smelling these weird smells? My bf doesn’t smell anything I’m smelling btw !

Also today will be my last day that I’m supposed to be ovulating!!
