Hi Imwarr,
I'm not leaking yet (mmm!), but my friend has 3 children and started about 20 weeks, so it must just depend on the individual.
On the subject of gender, I was like you, thinking I would've preferred a girl but not minding that much really.
We found out it was a boy last week and I'm so excited, it's really great just to know what it is. You must let us know!
