I'm 15 weeks and mine started leaking last night. Early I know! It was quite heavy but seems to have settled down now. Mine have been quite dry too, you can use a nipple cream while your pregnant if it bothers you :)
I started leading around 23 weeks & it's probably dry skin around the nipples.I have that happen all the time & I rub Vaseline on them & it stops the dry itch & scaling 4 days. I am now 35 weeks.
That's probably dried colostrum. That's what i noticed first around 24ish weeks. Now i'm 35+3 weeks and am starting to leak through my bras.... :/
Its directly on the tip on the nipple(the whitesh stuff) and it tends to be dry around it as well. I'm 27 and I haven't leaked but it tingles a lot. I'll be sitting there and it will feel like my nipple fell asleep and woke back up.
I have that same stuff in my nipples too. I dont know what it is though i haven't had any leaking or anything and I'm 39weeks
