Engorged

My baby is 2 month old and we stopped breastfeeding yesterday. I was going to slowly transition her to formula, but she is doing so good on it that I am just going to keep going with it and stop breastfeeding all together.

But my boobs are so engorged and sore. I have cabbage on them now, is there anything else I can do? Should I pump a little bit? Or do I tough it out? I’m just confused on how this works. Will the engorgement just go away on its on? And how long does this last?

Sorry for all the questions 😩
