Do not go into the weekend with your PEG hurting.  Call your gastro and get into see him/her ASAP.  My PEG hurt like heck when it was first put in and I just thought that was the way it was and suffered.  At my one week follow up appointment the PA had a fit - the PEG was too tight.  She told me I should have called after two days of pain.  So call - Now!  Good Luck - keep your chin up.  You'll make it.
