Green Feces, What To Do?

I have had it for 6 days. i go every too days im 15, the crap stinks like sweat/armpits. So it would have started tuesday. I ate a bag of sour patch kids on tuesday thats about 100 candies that are full of colour i hardly ever eat them so maybe it thats? and then on friday i ate a bag of gummy livesavers. I have a cold that started saturday... could a cold cause that? im worried i dont want to go to the doc cause he might make me doo blood test which i hate, also it used to be limegreen and now its dark green like, the top of broccliee. what iis it? will it go away? i have a bit of stomach pain also
