So at 13 weeks 1 day I had this ultrasound and the tech marked what she thought were boy parts and told me that the nub isn’t still swollen at this point. The image is blurry to me and I think I can see the nub in the bottom picture just to the right under the bright white spot but I’ve never been good at nub theory. I’m just not sure I believe it’s a boy. We want a boy but I don’t want to get my hopes up too much because it was so early and I really thought boys and girls were still swollen at 13 weeks. What do you think? Boy or girl?
