There is a naturopath at a chemist that I visited the other day, we talked for a while and she said that she could run some test for me. I explained to her that I was still breastfeeding and she said that I could start on some kelp tablets for now, to boost my thyroid function which can aid my metabolism, and that when I finished BF that I could try some other things. I'm looking forward to having a proper consultation with her to see what she thinks is going on with my body.
