Hi I'm Battling With Fatigue, I Look Like I've Been

Hi I'm battling with fatigue, I look like I've been a pin cushion on my arms. My period has come two weeks early. I've recently had a full bloods taken and they came back normal? I take a multi vitamin as well as extra vitamin d and calcium . I'm a stay at home mum of four and I run and train 4 days + a week so would consider myself healthy. I've tried reducing excercise and had no change in how I feel.
