Gender mix up

Elizabeth • Mama to one precious little boy & due July 2020

I posted about this previously but didn't attach pictures from my ultrasound and wanted other opinions. At our 19 week appt we were told we are having a boy and it was confirmed with the picture I attached. Now at 28 weeks I went in for an ultrasound and they were unable to see a penis. They are afraid that it was just swelling in the genitals the first time. Either way, I'll be happy but we've spent quite a bit on clothes and items as you can imagine. Anyone out there an ultrasound tech or just want to take a look at the original ultrasound and tell me what you think that would be great! Also, I didn't get a picture this 2nd time so I don't have much to compare the first one too.

Thank you!
