I have read that you are more prone to bleeding gums while pregnant - maybe with the excess saliva and some blood from your gums it looks worse than it is.. but I would call your dr or a dentist.
I don't think so....I would call your doctor....are you coughing?? I mean I'm no doctor so I'm not sure but I don't think that's normal. Your blood supply is very high right now so you may simply have an irritated throat or mouth sore that's bleeding more than it normally would...but I would call the doctor.
