By all means, I am not a doctor. However, your post is very vague. Given on the vague post with no symptoms I can only offer a few words. Sometimes a patient will have symptoms, but all tests show "normal". A secret is to look at the testing itself. For example, when I was diagnosed with Diabetes, my only symptom: no menestration (go figure). It took 6 months to catch, as everything came back "Normal." 6 months later, the doctor was just going through charts and looking at things during a well being check up. Anyhow, it was discovered the blood work was yes, normal, but high. So he decided to put me on a diabetic medication that would give my menestration back if I was diabetic, but not hurt my body if I was not diabetic. I had my cycle back that month. Answer was "she's diabetic." Some people just like to be unique...not match any symptoms but be something. So I can only suggest to look at the testing itself for any abnormalities (even if tests say "normal") and prayer and second opinions and specialists.
