Your aim is to make sure she is fully balnced prior to the treatment so I would give her a full reflexology treatment, once a week for four weeks to get her relaxed and in balance before the treatment starts. It is a very stressful time so the relaxation is as important as the rest of the treatment . I would do lots of work on the solar plexus and the spine and a lot of monotonous movements to help her relax.
As regards the IVF, you want to make sure her endocrine system is in balance so I would work the pituitary, thyroid, thymus, adrenal, uterus, and ovaries. I would also work the elimination systems to remove all toxins and waste, lymhatic, urinay and digestive. I would also work the fallopian tubes.
I would be inclined to talk about her treatment with her and carry on with the treatment if only for relaxation as well while she is going through it all.
Good luck! let us know how it goes.
