Ideal weight for Girl sway!!!

Hi Everyone, I am on the Le diet and looking at planning my first sway in August, however I am nervous about my weight, although I will have a stone off by then I wondered what weights everyone was when they got there girl? I am trying not to obssess but I am worried I should be a lot thinner so maybe I should put my sway off till 2013 as Sep-Nov are boy months were I live. Any advise would be great x

Between 18.5-20 BMI ais best. Lower than 18.5 will still sway pink but may affect fertlity negatively and keep you from getting pg.

I only lost 3 lbs before conceiving my daugher, but I had gained weight with 3 of the 4 boy conceptions and I was at my lowest conception weight ever (123 lbs.)
