exclusively breast pumping- to stop or not

Erica
Working mom Looking for opinions! 
My little girl will be 5 months next Friday. I decided Friday I was going to stop pumping. Now I'm second guessing my decision :/ I have enough breast milk for 80 days (2400oz) so she will be almost 7 months. Do 7 month old babies still take a bottle? If so how much? She is currently eating rice cereal 2x a day. And plan to start stage 1 baby food this week. 
Sitting here with painfully engorged breast! To pump or not to pump! 
Other info: baby does not have colic or reflux. She is 16lbs born 6-14-16
