I was told at 13 weeks I was having a girl and I am having a girl still:)
At 17 weeks, not that it isn't impossible, but more than likely what you were told you are having, really is what you're having. Keep an eye out at your next ultrasound just to be sure, but I am sure you're sticking with pink then! Congrats!
Thats what i sed.. he wanted a girl so did i i guess he is in shock since we have a 3year old boy and know a girl on the way :)
I found out at 18 weeks and she's still a girl! 3 lines are 3 lines :) I'd say it won't change.
