My god.. Uncalled for stress. Boy or girl depends on ur hb sperm.. U can't do much. Wat happen if ur bb is a girl?
I prefer a boy too. But I tell myself I want a healthy baby. If really boy, it's a big bonus for me. If girl, I know in future she will be as filial as me.
Btw, i followed those techniques to conceive a boy.. Anyway u just wait for 5m to scan the gender.
