Awe you are a sweet pea! Yes, waiting a few weeks sounds like a good idea. My OB wouldn't do early scans at 6/7 weeks like a lot in my area do because it can cause a lot of unneeded stress if you are off a few days on OV date, and things were fine at a scan 2 weeks later.
So exciting you get to see your little blip soon. That is still my favorite scan of Finn. I may have to dig it out and go look at it!!
