Producing milk at 18 weeks pregnant?!

[Novia]

What the title says really! I'm guessing it's colostrum rather than actual milk, but is this normal?

It's my first pregnancy so I have no basis of comparison, but it seems very early; should I be concerned...?

Perfectly normal, people often don't notice. I had it even earlier with my second, which was surprising!

Thanks incyspider! It's probably a silly question - but when it's so early, there isn't a chance it will run out is there?!

No chance of it running out, your body is just getting ready at this point. As soon as your baby is born your body starts producing it on demand. So don't worry :)
