Breastfeeding

I have a 3 week old newborn. I tried breastfeeding and she didn't like to struggle. So I started pumping but I only pump 1oz or less. I've tried multiple time to breasygeed but she cries so intense. I need help!!! Suggestions on how to get more milk while pumping?? How to help her like breastfeeding??? Thank you ladies!!!
