Ardana's chart she uses was correct for 2 of my friends last year and a girl I met on here was predicted girl. So far she has had 2 ultrasounds that confirm girl. She predicted girl for me and I will scream if she is correct for me ;-) I am sure I will be the one who is wrong though.
Peony Princess said I was perfectly in a girl sign, which I knew per my jonas calendar I got from a gal on here for a whole year.
I go for an elective scan this Friday at noon. I will be sure and report back either way. Prepared to hear "It's a boy" LOL!
