maybe tmi but colostrum

Almost 22 weeks pregnant and I wake up leaking. It's really not a huge deal but I just didn't know if this is a whole lot to be leaking at 22 weeks. I leak through my shirt and onto our sheets (which are now in the washer) 😂😂😂 I feel like I'm going to have to start sleeping on a towel. Any other Momma's having the same issue?
