12 weeks and no scan

Hello I was wondering if anyone else is still waiting for there first scan? I think I am about 12 weeks today I have had some pregnancy symptoms like sickness and a really bad hormone rash but still don't have a scan for another 1 week. I know I shouldn't worry but I can't enjoy just now as I don't know if there is a heartbeat or baby is ok :/ I have never had any bleeding or reason to worry but still can't relax at the moment.
