Just a cautionary point. If you do have blood work from your GP and he/she finds your thyroid levels to be off PLEASEPLEASEPLEASE go see an endocronologist. GP may think they can deal with a thyroid issue but there is sooooo much involved that there is no way they can. Only a good endo can tell you why you would have the SYMPTOMS of Hypo or Hyper thyroid. Ask me how I know!!!
