Did I catch a cold or is it flu ?

I've been in my bed all morning, can't walk around with this terrible headache. Still don't get if my nose is runny or stuffy, depends, it's both actually. My eyes are watery. I'm sneezing and coughing and my chest hurts when I cough or laugh.
I don't think I have a fever, or at least not a high one.
My parents aren't here, so...Don't really know what to do, it's been two days already, but it was more like a cold, these past days...I don't know, I could go to school, and walk around even though I had a headache. Now I really can't.
There's no more paracetamol, I took all of it these past days ( 2 or 3 a day )
But I have Ibuprofen, will it work fine ?
I really need help. What should I do ?
