NNo that isn't normal . You should call your Dr sweetie.
Leeking what? If its colostrum (from your boobs) it is completely normal. I started at about that time as well.
Im 28+5 and haven't started yet. But my sister was 17 weeks when she started. It's different for every woman.
Leaking discharge? Or colostrum? Discharge is normal, because of increased estrogen and blood flow to your uterus you will have a lot more discharge. As for colostrum, it's also normal.
