You are using the best herbs available and you obviously have a problem. The problem is the opinion of your naturopath who is preventing you from making your mind up about what to do. Naturopaths like everyone else have opinions; some of which are justified and others are just prejudice. Another naturopath may be all for Liver Flushing which leaves you with the problem of making your own mind up. It certainly sounds from what you have described that you have stale bile and possibly a few stones. The consensus of the group would be to complete a programme of flushing before you get pregnant again.
