Need help with Ramzi Method!

Hi! My husband had "forbidden me" from finding out the gender of our baby.  I've heard the Ramzi method is 97% accurate.  I had an abdominal ultrasound at 8 weeks.  For the life of me though I can't tell what side the placenta is on! I "think" I'm having a boy but if anyone can give me their thoughts that would be AWESOME!!!
