Ultrasound question

Question about ultrasounds

Im 10w 4d with #2

I had irregular periods when i got.my bfp so my midwife.ordered a dating ultrasound the nezt day because i had no period to really go off of.

The ultrasound showed 7w 5d

And a heartbeat of 167 i go back at 12weeks.

My question is, when would i have another ultrasound. I seen most had them at 12w. So will i be possibly getting another one. Or will they wait until second trimester?

I had 3 with my first but my first ultrasound was a dating ultrasound as well because of no period thing but i ended up being 12 weeks.

In ohio,usa btw.
