Milk milk milk!

Hi ladies. I'm 31 weeks pregnant and was just wondering when did you all start producing milk?

All through out the pregnancy I haven't felt like my boobs have increased much and I'm hearing lots of ladies who say they start leaking!! I am just starting to panic that I'm behind with the milk!

It's not that I exactly want to start leaking milk everywhere but just to know I'm normal or that other ladies have been in the sake situation as me would be great!

Thanks!! Xx
