Why do my fingers hurt so bad after fretting a chord a few times?

I am on day 2 of learning chords on the guitar. I know that finger soreness comes with the territory but omg! I can't play a chord more than a few times without excruciating pain in my fingers. Is it normal to have such bad pain in only a matter of about 5 minutes? I've read about people sayin that they hurt after about 30 min. of practicing but I can't even get passed 10minutes. Should I press through the pain and still practice for 20-30 min. anyway? Thanks ahead of time.
