Thanks Donna. Does he have the metalic taste all day, or just after he has taken one? The thing is, I'm trying to concieve at the moment and I've had the metalic taste from 3 days after I started taking them, which was 6 days past ovulation, so I'm hoping the metalic taste is a symptom of pregnancy, rather than the antibiotics, lol. I won't find out if I am untill weds though.
