I think it is totally normal to leak colostrum quite early on. With my DD mine started leaking a little at 19weeks. Am currently preg with DC2 and this time it started about 16 weeks.Mine is just slightly drippy it doesn't flow out although I guess each person is different.
Hello, I started at 22 weeks - so not quite as early as you, but still early! Its completley normal - get some thin breast pads (or i just use oval cotton pads, as its usually small amounts during the day for me).
I leak loads at night when my boobs are pressed against my arm... and have certainly noticed the leaking when i hear babies crying. can't wait till i've got an actual baby to feed.
I leaked colostrum really early (this my DC2) but it has stopped.. so I don't think it means you will continue to leak through pregnancy, although this is possible. I think at early stages your hormones are in overdrive and they then settle down...
