When did you start pumping?

When did you guys start pumping? I’m 35 weeks and have been contacting on and off for two days and my ob said that baby girl is definitely coming early and that between 34-37 weeks there’s a good possibility she wouldn’t have to go to the nicu but if she does it would only be for a week or two at most. I want to have some colostrum for her while she’s there, if she has to be in the nicu. I’m thinking it should be alright to pump since she’s already making her way out early. But wanted other peoples thoughts!
