First ultrasound

What's the earliest you have had an ultrasound? Tomorrow I will be 7 weeks and it's my first doctors appointment...I'm really hoping we can do one then but obviously I'll wait if I have to. I'm just so excited, this is our first pregnancy and I am so anxious (in a good way) for everything to happen. Did any of you have early ultrasounds? Also, any important questions I should ask? I have so many in my mind but I'm afraid I'll forget them all. I know my doctor will tell me everything but just in case, anything weird but important I should ask? Ugh okay, I'm just nervous 😆 all responses welcome!!
