My TSH is 3.6, I have high cholestrol & triglycerides- could I still have hypothyroidism?

I read up that hypo thyroidism normal range has been changed. It also affects cholestrol and triglycerides. Do u think I may still have hypothyroidism. I have clic symtoms- fatigue, lot of weight gain, puffed up face. I exercise for 45 minutes - 200 calories 3 times a week. No weight loss. I have fruits and veggies.
