your symptoms of pregnancy are going to change quite rapidly! i had the metalic taste only very early on, and that went away, along with all sorts of symptoms that come and go. also, i had bleeding early on this pregnancy (my 2nd) and had it checked out and everything was fine, no explanation for the bleed and it didnt happen again (very common!) stay positive! stay hopeful and hang in there till you see your doc. hope all is well :-)
