is it adam's apple or is it a thyroid condition ?

I am taking gym proteins which contain high amounts of whey and soy, i have started to take this protein around 5 days ago, i am 21 and i have started to go to the gym at the same period, my neck had no signs of Adam’s apple, i woke up this morning with what looks like an Adam’s apple, so what should i do exactly, is this condition related to my protein intake ? should i stop taking these protiens ? and if i do will my throat go back to its normal appearance or should i go to a doctor ?
thanks
