Considering a private 4D scan this weekend to confirm gender of our baby. I'm 17+3 days and will be 18+1 then. My regular 2D scan isn't until Dec 14 and I'm very anxious lol Have you ladies had experience with an early 4d? Is it worth it? With my son we did 33 weeks and he was all squished and we saw nothing :/ but I don't want to waste money.. Suggestions are appreciated :)
