Has anyone used breast pump along with EBF?

Hi, I am looking for some advice here. I'm a FTM & my LO is 8weeks old. I'm breastfeeding currently & want to start pumping and use bottles for him couple of times a day so that I can get some rest and also get things done.

I want to know how to start and what should be the routine like when to pump and how to store if I don't feed him as soon as pumping. Women my age in my family are judgemental af so here I'm looking for advice from fellow mamas.

TIA!
