Yeah - this is the suckiest bit of being pregnant!! It kills to wait so long for your first appt, but its just the way they do it in the public system.
I have my feelings for why they do this - but no need to go into here.
My dr doesn't discuss the results with me unless there is something out of the ordinary, so for me it was hearing nothing from 5-12w!!! Its a total killer, but you'll be fine.
They will likely give you a dating scan on your first checkup, so look forward to that. Its VERY exciting!!
