When do you normally go in for your 2nd ultrasound?

I supposedly went in for my first scan at 7-8 weeks but I turn out to be only 6 weeks and 5 days with a good heartbeat! My next ultrasound will be in 5-6 weeks and that’s October 18th. That seems so long from now. I’m currently 8 weeks and 4 days and I have to wait a good 4 weeks before I can see my baby again. It’s so hard to wait that long and not know how your baby is doing inbetween those weeks. I mean by then i should be 12 weeks and the OBGYN said it’ll be big enough to just do abdominal ultrasound instead of transvaginally. When did you guys all have your 2nd ultrasound?
