Early HCG and Gender Theory

Stephanie • Mother of a sweet little boy (11/13/16) and little girl (08/30/2018)! 2 MCs (12/20/2015 and 7/25/2017)

I read that higher HCG early on could point to a girl. This pregnancy I was well above the average and basically in twin range. Anyone know what they are having and what their HCG was around 5 weeks?
