Your concerns are warranted and should be addressed by your doctors. The combination of your age, a first pregnancy, celiac disease, hypothyroidism, diabetes and, most importantly your serious allergic disease, especially the recent response to peanuts, significantly increase the risk of your pregnancy; risk to you and to your baby. The flushing response with allergy testing and the recent "itchy face and trunk" are worrisome as they suggest that you are at significant risk for more serious reactions.
The non-allergic, non-respiratory problems can safely be managed by your family doctor, an internist or maybe even by your obstetrician (OB), if she is comfortable and trained to manage these types of diseases.
The asthma/allergy disease, as you have described it, is definitely beyond the expertise of your current doctors and should be managed by a board certified allergist with a high degree of experience with food allergy, including reduction of the risk of anaphylaxis.
I strongly recommend that you consider consultation with a medical school university hospital affiliated allergist specializing in food allergy. After your evaluation, such an individual could then work collaboratively with your local allergist. Such specialists would be found at the National Jewish Health in Denver, Colorado; at the Johns Hopkins Medical Center in Baltimore, Maryland; and at any of the Mayo Clinics, or Dr. Michael Kaliner at the Institute of Asthma and Allergy at the following address:
11002 VEIRS MILL RD #414 5454 WISCONSIN AVE. #700
WHEATON, MD 20902 CHEVY CHASE, MD 20815

It is my impression that your doctors, including the allergist, may not appreciate the seriousness of your situation. This is too important for you and your baby and your family to not take the steps necessary to protect all of you.
Thank you very much for your input. I really appreciate this. I guess I have been treating this as not so serious, but I realise from your response that it is.
I am in Philippines and don't have access to your Doctors. However, I will go back to my allergist and discuss your response with her and also ask her to help me work with my other doctors.
Thank you again the service you offer is really wonderful.
