Should i be worried?

Im 14 weeks and 2 days now and just got blood test results from hospital. Ive been realllly sick (nausea and vomiting, headache, dizziness, extreme fatigue, shortness of breath, etc).

One thing from the results that concerned me was my thyroid stimulating hormone level. The standard is .35-3.3 but mine is .07! I contacted my doctor who said not to worry because my T4 is within standard range but this is also the doctor who said theres no connection btwn progesterone and miscarriages (i read otherwise from many of you ladies here on glow after my mc in april).

Anyone have any ideas??? Google doesnt confirm what my doc said and my nurse friend isnt quite sure.
