Nub Guesses Please

Hi All-- I had this ultrasound done when I was at the latter part of 11 weeks-- so I know it may be too early to tell. I had another ultrasound yesterday when I was measuring 12 weeks, 5 days and I noticed two bright white lines several times throughout the ultrasound but only for a moment each time. However, at the end when I saw a picture of my baby from the feet up with its legs crossed, I may have saw a penis, but it was hard to really tell. I am not posting any of my pics from yesterday, because I'm fairly certain there isn't a nub in sight-- although I can post them if they would help. One of these pics kinda looks like a smaller penis with the longer line under it (maybe eventually the testicles) but I am not expert in this area. I obviously am hoping for a girl (based on my name), but my intuition is telling me to let that go. I had terrible GD with boy two so I am really trying not to suffer in the same way with this final baby. Its like I want to know and I don't want to know. Gah.
