Colostrum already?

I'm 24 weeks and for the last week man my breasts feel like they are growing. They were pretty sore first trimester but didn't feel like they grew. Now yesterday after I showered I noticed one breast leaked a little, I tried the other with my hand and sure enough must be colostrum already. Guessing that might be why my breasts feel bigger? Or maybe it's just that I'm finally gaining weight. Either way thought it was pretty cool my body is starting to get ready to feed my little one❤ I also don't remember this happening with my first 🤔 maybe I just wasn't as aware😊
