Ramzi method?

Erika • My one and only little was born 5.12.15 @ 37 weeks. 💙Extended breastfeeding, bed sharing, gentle parenting 💕
Anyone familiar with the Ramzi method to determine baby's sex? I'm curious about it but I'm not sure which side the placenta is on! Any ideas? I don't know head from feet on these ultrasounds & I definitely don't know what to look for with the placenta haha 
First pic is today's, 8+3. Second one is last week, 7+2! Thanks guys :)
