Products for bad breath? 😷

So two weeks ago I had one of my back upper teeth 🦷 taken out ouch 😣 yes I know, well I’ve been having really bad breath to the point where my husband has been maki big comments about it. I brush and floss everyday and he sees me but still since they took this tooth out I’ve been having bad breath. Sometimes he says it smells like blood sometimes I taste/smell it too. I’ve brush the area and blood comes out and after I rise 3 times there no blood. So idk if there’s something I can do or you can suggest please help
