This might sound a little unusual... but here goes. My partner is in a 'heavy metal' band, and occasionally I have performed with them as a vocalist, but it is not what most would call 'singing'. I have a very unfeminine sounding scream or growl, which is very desirable for that style of music. We are planning a show within a few weeks in which I would only be performing one song with the group. I am concerned about my baby... is it potentially dangerous to do this while pregnant?? please help!!!
