Don’t know if it works, but have a look at gender swaying. It explains, in theory, some ways to help sway the gender based on ovulation and when you have sex. Anecdotally, it kind of makes sense based on my pregnancy (boy) and my friend who has one of each!
I'm not sure anything actually helps to be honest it's more luck of the draw For me the chinise gender charts have matched up though
Well don't take my advice three boys in and pregnant again not sure what this one is good luck 🤞
