Leaking clear fluid from my breast when I do stimulation!

So I was reading up on nipple stimulation and tried it and this clear stuff started coming out of my nipples. More my right then left one but I heard it’s called colostrum. I stopped once I saw it cause I was like freaking out cause I’ve never seen anything come out of my nipple before. But for some reason it was a little funny to me and my fiancé cause we’ve never seen it. And I was like WTF my nipple is leaking and we just started laughing. I thought it was pretty cool to see my body do these odd things but if I guess my question is does it mean the baby is coming sooner than expected since I do have this stuff or has it been there the whole time and I just haven’t known it 🤔
