i had first one at 8th week but that was because if previous losses. Else in Uk you have only 2 U/S at 12 and 20 weeks.
I had my first u/s at 11 weeks. but since you do have irregular periods they might get you in early for one.
I had my first ultrasound at 6 weeks but I found put I was pregnant at just 4 weeks and had started bleeding quite heavily. But bubbas okay! 16 weeks and 4 days. :-)
I had my first ultrasound at my first doctors appt at 8weeks
I wish I had u/s's during the early stages!!! I was 21 weeks when I had my first u/s.
Because I'd miscarried just before falling again I had a scan at 7 weeks, only because I'd not actually had a period since the miscarriage and they had no idea how far along I was. It's possible that they will refer you to check.
After my results came back positive I was scheduled for an ultrasound when I was 7 weeks
They did my first ultrasound at my first apointment I was 9 weeks and 6 days pregnant at the time
