Hi and welcome! Sorry I am late on this one, things have been so hectic around here I have not been on the board at all.
You already have some great advice, and yes, the GP could order those tests for you. Any idea when you might see the specialist? At this point in your life, things can change quickly, or they may stay the same for quite awhile yet, it is so hard to know even with the tests. It isn't too late though, it can certainly still happen. :-)
