Nipple leakage sorry if it's tmi...

Ladies when did your nipples start to leak? I'm 20+6 and I'm laying in bed and looking on this app. I'm laying with no shirt or bra so when I lift my arm to type I rubbed it against my nipple. I felt something wet and said wtf. So I turn on my flashlight to look but it looks normal/dry so I wipe again and felt a little bit wet. So i squeeze my boob just a little and stuff came out. It's clear and it's just a little not a lot. Is this colostrum coming in already this is the first time it's happened?
