Strictly pumping from brith?

I’m a little confused on how to do that!

Some background: I was so set on breast feeding when I was pregnant with my first - then he was born and that didn’t quite work out. I did try but I made it a day and a half - we both spent nearly the entirety of each attempted session crying. He would latch, I would wince and cry then he would let go maybe 30 seconds later and cry for what felt like an eternity before he would latch again and repeat. My nipples are sort of flat and a nipple shield solved that but things still played out the same. I don’t know what was really the heart of the issue, everyone who tried to help me in the hospital just insisted I was doing it wrong (I was young, but I did my research, I followed all directions given to me and tried so hard with him. Looking back I am still baffled by how I was just doing it wrong...). Anyway I had no clue that I could pump (I mean I knew what it was but didn’t realize it was an option for me) so we put him on formula and it was all okay.

Well I’m pregnant now so this time: I would love to try again, but I don’t know if I can breastfeed directly. The pain was so much for me and it was so hard for me to hear my baby cry because I couldn’t do for him what my body is designed to do for him. HOWEVER, I’ve become pretty interested and accustomed to exclusively pumping! I’ve read the pain is pretty minimal and then I can physically see that my baby is getting what they need (something I did enjoy about formula feeding). But how do I do this with a newborn? Do I pump before they are born, can you even get anything? I know it’s just colostrum at first but can I pump that, can it be given from a bottle? Or do I just pump immediately after baby is born and offer it then?

I understand pumping “schedules” for supply, supplements, storage etc. I’m just so confused about the first day or few days of exclusively pumping from birth for a newborn. Any insight? Thanks!

(I’m sorry this is soooo long and I hope it’s okay to post this here)
