When ever I log on here, I see the majority of posts are "nub" or "Ramzi" theories. I've heard it's really hard to determine what the actual sex is during the first trimester and early second semester. For example, my obgyn says we won't know until 20 weeks because even looking at the US earlier than that, sexes of babies have been incorrectly interpreted. Isn't it most important that ourselves and  the baby is healthy rather than fixating on what the gender might be? I guess that's just me and maybe I'm being hormonal but just seems weird to guess the sex so early on...
