Leaking Colostrum

Al

This past week I have began leaking colostrum. It’s mostly at night or while I’m relaxing around the house. My question is, can I pump this? Little bits each day, or can it cause preterm labor? I have heard both things. I plan on talking to my doctor about it on the 29th at my next appointment but wondered what you all have been told. I am 22 weeks today 10/19
