When did you first time moms start producing colostrum?

I was really early. Before my second trimester

me I was 35 weeks with this one still haven't and I'm 24 weeks

with my first it was around 31-32 weeks.

I'm a ftm and I started in my second trimester I don't know when exactly

I'm a ftm and started at 27 weeks

I think I first noticed leaking around 19-20 weeks

I noticed my bra had leaks last week at like 25 ..

during my first pregnancy, it was around 5 months... to the point that I had to start wearing breast pads... but, I'm further this time and barely leak (3rd baby).
