Can I ask how you guess from a profile picture? I had always thought it was a potty shot that showed, but my youngest is almost 15 so I'm sure there are new tell tale signs that have been discovered since then? I have a 12 week potty shot, but the tech told me that it was way too early to tell. I'm almost 18 weeks now, but haven't seen a doc besides that one ER visit at 12 weeks so not even sure when they do an actual scan to see gender. Thanks!
