Cracked Rib!

I'm currently 31w 5d with twins. I now have a cracked rib which is way more painful than I could ever explain. Unfortunately, there is nothing they can do for it except meds and ice. When I saw my primary doctor today they said it could take 6 weeks or longer to fully heal. I've had my heart set on vaginal delivery and my doctor is okay with that. But my question is how in the world will I be able to put enough effort into pushing if I can barely wipe my own butt? 😂 Anyone else experience this? Were you able to push? Did you do an epidural, pain meds, or natural?
