Congratulations!  My idea about this, though, is fioricet can be safely taken while pregnant.  I was on it before and my doctor still prescribed me it since it doesn’t have any ingredient that  can harm an unborn child.  You should consult this to your doctor for further understanding and for more info.  Also, have you tried placing a wet towel on your face?  And of course, stay in a quiet, dark room for further relaxation.
