21 weeks and already leaking?!

Veronica 💙

I’m 21 weeks as the title says and I noticed yesterday before I showered I looked in the mirror and my nipples looked shiny so I took a good look and saw clear stuff was leaking out. Is it normal to start lactating this early ? Shouldn’t it have started around 30-35 weeks into the pregnancy? I’m asking because my first pregnancy I started around that time, 30-35 weeks 😬
