I came across this method and am super excited. It is not 100% accurate of course, but when I reviewed my 18 months old ultrasound from when I had it done at 10 weeks, his is definitely on the right, and he is definitely a boy.

So I have uploaded the 7 week ultrasound I had for all of you to guess.

My next ultrasound is on the 18th! I plan on asking them then what side my placenta is on. So weigh in and help me pass the time.
