I'm home!
Welcome home Sara!
As leslie said, the gas pains subside within a few days, walk as much as you can, it will help with the pains and forces them out faster. Gas-X has also helped some people, but I didnt really notice any difference with it but defintely did with the walking.
BMs seem to be different for everyone, I had the first one in the hospital and it was pretty normal.I would have some benefiber or something similar available for a while too, I know I needed it in the beginning!
Dont worry, it gets so much easier and you'll be so glad you did this before long.
