What Does This Blood Test Report Indicate?

Hi there. My bloodwork has high vpm (in french) and i am an endurance athlete. First blood work platelets were 131. Vpm 10.8. Then 2 months later platlets 152 and vpm 12.1. What does this all mean? I have been very fatigue lately with headaches. I am being treated for low ferratin levels and thyroid even though my tsh is only 4.4. Ferratin is 23. Not sure if the synthroid is safe for my heart and it is making me feel nervous. Thanks
