Later....basically I would have written what Jean already said about "allergy tests"...not always the most reliable. Consider an elimination diet keeping the common allergens out (that would be all grains, dairy and eggs) but then test the others on you. E.g. Eliminate coconut for three weeks...then challenge with a 3 day reintroduction. Chris Kresser had good instructions how to do one. If you are nursing you need extra energy. Doesn’t seem an ideal time to test allergens and lose weight also,a bit too strict for now.
