Mine started at 16 weeks.
Completely normal. With my first I started leaking around 25weeks. With this pregnancy I started leaking at 10 weeks. Its a good sign if you plan to breastfeed :)
I started leaking around 28 weeks.
I've starting leaking, and im almost 20 weeks, it's called colostrum. You're body's just getting ready for the baby. But it's not good to try and make it come out. It can cause preterm labor.
Totally normal as early as sixteen weeks for a first time mom.
Its different for everyone mine started at 14 weeks some people dont start till baby is here
