I remember this too

A real metallic taste - my grandmother said you got it if you were carrying a boy... but I think its just an old wives tale ... Although I DID have a boy

I do remember it getting that bad one day that I peeled an onion and ate it like an apple in an attempt to have ANY other taste in my mouth

Very sad, I know!

I couldn't get rid of it - and I blame a lot of my m/s on it - I'm sure it was that taste that made me even have the morning sickness.

Good news is that it was gone as soon as I hit the 12 weeks... and my morning sickness went with it
