Gender scan today! Worried about gender disappointment

Manda
I've got a private gender scan today in a few hours ill be 16 weeks 1 day. It's our second baby we already have a 2 year old son. I genuinely do just want a healthy baby. However my husband would love another little boy, whilst the rest of my family (my nanna and mother mainly) are hoping for a girl. I know either way I will be happy but I can't help but worry about other people being disappointed and giving me negative comments and making me feel bad.... I don't know what it is about baby boys but people seem to make so many rude comments about not wanting 2 boys & it really upsets me. I'm almost wishing I hadn't booked a scan now as even if I'm happy I worry someone in the family is going to be a nightmare and make rubbish comments. Any advice?
