Most women won't produce milk in till after the baby is born if they do leak be for that it's just a clear liquid
I started to leak at 21 weeks and when I told people they all thought it was weird because it usually happens after. My nurse said it was rare everone leaks at different times. And it is just clear drops sometimes clear with a little but of white! I'm now 23 weeks and its a little more than drops now lol
I started leaking at 18 weeks. But it was only clear liquid which is colostrum. Now that I'm 37+5 I leak a little bit of milk but most of it is colostrum.
