holy heartburn batman

 Okay so I am newly pregnant (about 8 weeks).  I am having lots of gas and for me that's a crazy amount.  I burp constantly after everything I eat and drink (including water).  Now I am having horrible heartburn.  It is mostly in the evening and it is so bad that my throat hurts.  I have morning (all day sickness) too and I throw up everyday.  Most of the time it is just dry heaving.  Is there anything I can do, take, stop doing to make this better.  I eat a pretty bland diet as it is and take tums, neither of which is really working so well.  I appriciate any advice I can get.
Thanks
