Never did for me. Said I would have a boy. Said the same for my sister as well, and we both have girls. My family always just did it for fun since there's no truth behind any of it.
I did that with my sister and it went from side to side and we found out a few weeks ago that it's a boy
i had a black ring around my belly button and my linea nigra went from my pubic bone all the way in between my breasts haha! and i had a girl..so maybe its true!
She's talkin bout if u place a ring on a string n hold it over ur tummy...LOL, but I do kno wat ur talk about
Told me I was having a boy. So did the chinese calendar. My linea nigra goes to my belly button only, which is indicative of a girl. My ultrasound confirmed a girl at 18w.
