How to link my aws cloudformation and my DNS

Hi, here is my problem,

I've been trying to switch from Hostgator hosting to AWS with wp template in cloud formation. I have created a stack in cloudformation, then I asossiated an elastic IP to the EC2 instance. After that I changed the nameservers in GoDaddy to NS73.DOMAINCONTROL.COM and created new A record pointing to the elastic ip. 2 days have passed since I've made the changes and my blog home page still shows GoDaddy's page. Please help me find what have I done wrong :(
