Cerebral palsy

My grandmother commented on how stiff my 10 week old daughter was and my mother commented on how she always has a tight fist. I did some googling (really bad idea) but as it was a bad idea I'm now stressing because all the 'what you may notice for  spastic-type cerebral palsy fits my did to a T. I can't get into the doctors for another two days and I'm in tears I know I should jump to conclusions but it's hard when that's the only thing popping up in search. 
Has anyone come across this or their baby suffered from this
