Weird Poop/breastfeeding concerns/advice?

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​My baby is mostly breast-fed but he gets one two ounce bottle a day when I feel like he can’t get any more milk out of me. I know I have milk left after fussy-feeds because I can hand express I bit more after. But he won’t go back on to feed again. I’ve had a bad relationship with pumping because It takes forever and it seems like no milk comes out and when it does I’ve had to do breast compressions and all to get even 2 oz out of one breast. Why do I feel like my baby can’t get all of the milk out on his own? (Should I go to an LC to see what’s going on?)

Also, today his poop has been off as well. Normally it’s mustard yellow and mushy and looks like EBF poop. Today it’s more green and it seems more seedy than normal...is it the foremilk/hindmilk problem? Or is it because he’s not getting enough? I’ll post a picture of his most recent diaper.
