Nub(?!) at 20 weeks?

Soo, I had my 20 week scan this past Tuesday. I am team green so I didn't find out the gender :happy: The tech had a hard time getting the baby's spine measured, because of the position the baby was in, so she spent quite a bit of time looking at the bottom part of the spine! I could see the bum/pelvic area quite well, and noticed what looked like a nub, a flat nub. Didn't think much of it at the time, but it was there, kept seeing it, sometimes for a couple seconds at a time. Once I got home, I started looking on "gender guessing" sites, and came across side profile shots of girls (clitoris), and they looked like my scan! Unfortunately, I don't have a picture from my scan :( Just wondering if anyone has had the same happen. I realize potty shots are best for gender determination at 20 weeks, and it's possible I was just seeing a leg. I was so convinced I was having a boy, and now I am back to 50/50, lol. So, that's good! Any insight/thoughts appreciated! Have a good day :)
