Do I have PCOS?????

I have been tested for it and the doctors tell me NO?? But my body is telling me YES?? What gives?? I have several of the symptoms that would say I have PCOS such as: infertility, odd hair growth, skin tags, bowel issues, weight gain mainly in stomach,and horrible acne on my jawline. The doctors have given me blood test which did not show I recently went to see a Neuropathic Doctor she agrees that my symptoms are pointing to YES I have PCOS. She said that the levels they test for can change depending on the time of day and which day of your cycle you are on. It is still possible that is my problem. I also spoke with my cousin over Easter and she is having the same issues and she spoke with a friend who is a Holistic Chiropractor. She told her the same thing and told her that a saliva test is more accurate. I had never even heard of the saliva test. I was happy to find out through research that my diet plan is what is reccomended for someone with PCOS. I am hoping with the healthy changes I am making that I will increase my chances of becoming a mother.
