First Ultrasound

So I got my BFP after TTC for 4 months last Wednesday.. Yayyy.. I'm 4 weeks and 1 day and I've already gone to the doctor to confirm. I'm so excited and anxious for my first ultrasound but they are making me go through 2 other appointments before I can even schedule my ultrasound, by the time I have one I will probably be about 8 or 9 weeks.. So I was just wondering how far along will some of you ladies be when your first ultrasound is scheduled? And what your doctor's procedures are regarding scheduling your first ultrasound.
