Ramzi theory in second trimester?

Jane
My spouse and I want to keep the gender a surprise for Labor Day but we can't help but look up old wives tales and etc to try and guess the baby beforehand. We had our second ultrasound today (22w4d) and the tech told us my placenta was on the left top section of my uterus. I'm just curious if the Ramzi theory was accurate for anyone else? I felt like this whole time I was having a boy but now I just don't know lol
