Good Faith Estimate timeline

I submitted my agreed upon contract to my lender 7 days ago (5 business days) for a house I am buying. I have already been pre-approved for this loan. My Realtor is pushing me to get the good faith estimate to be on file. My lender has sent me an email saying it would be ready the last 3 days, but I still do not have it. Is this something that should be ready rather quickly, or is my Realtor a little over anxious. Closing date is 2 months away, so there is plenty of time.
