Chinese Gender Chart. True or False?

Hello all; I've entered my information on the Chinese Gender Chart and it says my baby is a girl. It says it's "over 90% accurate" lol but I just wanted to know if it's actually correct for anyone who already knows the sex of their baby ☺️ I know I have to wait til 18-20 weeks to get a definite; but I'm just curious as to what it said for the rest of you 🎀 so just find your "age at conception" and "month of conception" and let's get these predictions predicting lol
