So I had an ultrasound done last night at the hospital (had some issues going on but everything is great!) and I guess hospitals don't give you sonogram photos, anyway- my DH snuck in a couple of pics. I heard about the Ramzi gender method or something like that? I know it's not 100% but it'd be nice to think about! :) does anybody know!? Or have any ideas?
